Corsa Sport Rain - Review

Underrated  - Corsa Sport Rain
I recently gave my underbone motorbike, a Modenas Kriss 110 to a friend's son as he will need it for his commuting at his local university. Sent the bike for a service as it was almost not ridden since the Pandemic, and with the old set of tires already showing sign of cracking on the side wall. It is only right to give the bike in a safe working condition to someone you considered to be your family. The previous tire was the Pirelli City Angel. Yes, I uses expensive rubber even for a small bike - again, safety always first!
Handsome. 2019 new tire
Taking into consideration where the bike will be used which is near the coast line and has more rain than expected. I've decided to change both the front and back with a well known rain tire that were well rated by the Grab/FoodPanda/Lazada/Shopee riders. The Corsa Sport Rain came highly reccomened for dry and wet handling, apart from being a mileage eater - everything a student would need in terms of economy and safety.
The Angel City with at least 50% remaining
The Angel City likely has seen close to 10k km of usage, and still solidly threaded. Only giveaway to the safety is the sidewall cracking/drying up. This also meant that the wet grip is greatly compromised as the compound has hardened up and unable to bite into the tarmac when wet. So do not compromise on tires.
Spot the line cracks along the lettering
Priced at about RM120 for back and RM110 for front including installation, the work/job was completed while the engine oil was changed and all moving parts checked for freeplay. Luckily the sprocket set and chain is still new (last changed 2019 and not went past 10k km), so the only cost for this visit today remain to be the tire, engine oil and spark plug.

Very convincing thread for rain and dry weather

The Front tire was replaced at the same time, and rightly so as different thread on motorbike can be detrimental to the handling due to different level of grip. Also, the sidewall was already showing sign of  failure/cracking and changing it with the rear is the only right thing to do for safety.

Old Angel City

New Corsa Sport Rain

Now, a bit of Corsa Sport Rain. The name gives the impression of a very continental feel, only that it is a proud product from Indonesia and has many years of experience. We all know the amount of motorcycles there are in Indonesia, and this is indeed a good indication of the usability and R&D that may had went into the design as they share similar weather as us. Read more about them here

My experience of using this is fairly limited to about 50km as I ride it to ensure everything is ok. First feel is that the tire felt good and grips pretty well on turning. My benchmark is of course the older Dunlop all purpose tire and the Angel City, which in my opinion is a huge safety consideration in rain for me. Braking distance was indeed better than the aging Angel City, and the start-stop typical of riding a motorbike provide good indication of power transfer and comfort over usual road bumps.

Hopefully, the new owner will enjoy the ride!

Pirelli DIABLO™ ROSSO SCOOTER - New Set

New rubber, lets go!

Those of you following this write up will know that I first installed this set of tire on March 2019 and has provided two reviews including the long term usage here on December 2021. The tire has since done close to 13k+ km and well needed for  replacement.

New at KM10 March 2019

October 2022 at 13K++ KM
The front tire was surprisingly still with at least 50% thread left. This meant I could still use it in my daily commuting and change both tires within the next 3-years. By then, the front will still be within the 6-years window but I will change it if there are sign of physical stress such as side wall cracks. It is not worth to take the risk for a few hundred savings.

Front new
Front as of October 2022. More than 50% left. Good condition

The process to change the tire was less than 30mins. I kept reminding myself that it is not like changing a bicycle tire as on a scooter, the mechanic has to remove everything that links to the wheels, including exhaust and the brake sets as they share common mounting points. Also, this is a good opportunity to check for any excessive wear and tear on the shaft or do any minor replacement if required. Was lucky none of it was required so the cost for the day remains to be the tire change and labor charges.

New replacement is week 22 of 2022. Not fresh tire but at least 3-months old in storage. Acceptable

Love the thread. Compound is proven on wet, dry, corner and straight!

Checking the disc, shaft and bearings


All ready again!
With new tire on the rear replaced, I am more confident and felt way safer to ride on any weather. Again, for commuting and very little to no aggressive riding, some may say this is an overkill - it may be as the one model down, the City Angel may be more suitable. But at RM20 price differences between the two, I am willing to pay for safety and solid wet and dry handling. Did I mention the stopping power and comfort?

ARC Roadster BelAir Helmet - Unboxing and Review

It's time to replace my 5 years old Givi helmet (primary user is my family) and a quick trip to Sentul motorbike town leads me to a brand locally known as ARC. It is not foreign to many local riders and the price point has always been pocket friendly. My initial plan was to replace it with another Givi (model is M30.3) with double visor but the pricing was about RM300. Which is a bit steep for a helmet that is worn once or twice by the kids and wife. We don't put a price on life (or head), so I was ready to commit to the White Givi M30.3 and that was when I decided to see what else were there on the rack with certification and most importantly, made in 2022 (helmet has lifespan)

Click Here For The Unboxing Video

The sales person at the shop was really helpful and brought a few helmets for our viewing and trying. The ARC Roadster caught Missus' eyes as it was simple and yet striking in design. The other two (Gracshaw and SGV) were put aside as we prefer something with micro-lock and not Double-D rings to secure the helmet chin strap. The ARC Roadster priced at RM250, which is slightly cheaper than Givi M30.3, and to our surprise the manufacturer is having a promotion and has placed the price of RM180 for a limited time. It was a no brainer decision then.
FS-720 in XXL

What it comes with
  • Box
  • Microfiber mixed polyester drawstring helmet bag
  • Helmet
  • Clear visor (installed)
  • Sunvisor (installed)
  • ARC tag
  • Hex-key to tighten/remove the visor
A bag, A helmet, A one-sheet instruction, A hex key and well, a box

I was hoping for a 40 pages manual. I love to read them

First Feel
The finishing is pretty good. Color (White) was even and with Red lining which were made of silicon. Not entirely sure why, as I am sure this will degrade fast especially for people that rides under the weather most of the time. But I put trust that the manufacturer will make it last the useful lifespan of the helmet (which is max 5 years). 
XXL @ 62cm - Fitting is slightly different compared to the same measurement Givi XL @ 62cm

Air-vent on the top via sliding mechanism

A nice touch with "Bel Air" which gives the impression of exclusivity. Silicon textured finishing. There is two smallish airvents at the bottom left and right

Rear View - White with Red-stripes gives really good look

ECE and JPJ sign off

Side view with visor down

The inner liner was good. I would say I was surprised it was textured and removable for washing. The cheek pad was thick, a good indication for both protection and sound (wind) isolation. I do ride with ear plugs if the journey is longer than 30mins.

Pretty good quality liner.
One other reason for choosing this ARC Roadster is because it comes with the sunvisor - this is singlehandedly a must have for me. Riding into sunlight or sunset is tough. Worse if it rains (well, it does rain and still have the sun shinning back at us). While it is missing a Pin-lock insert, you can get a generic liner to manage any fogging if you ride a lot in the rain.

With main visor up and sunvisor down
D-Rings or Ratchet system?
I much prefer micro-ratchet
The traditional system uses the Double-D ring, which requires a bit of work to get it secured. I've used both of them and has been spoilt by the micro-ratchet system which is easy to use and fast to remove. The structure of the system looked solid and doesn't seems like it will disengage not on purpose. Same reason why I invested in a Nolan N91 which is a flip-up and locks securely. You do not want the buckle to fail (or the flip to open) when you fall. Tested and secured system. Like them.
The Visor and locks
Anti-Scratch visor and with UV protection 
The Notch
If there is one thing that can be improved for the more premium feel is that the visor flipping system should have micro-adjustment which meant it will be secured at any position and not flip up or down depending on the wind-pressure. I noticed the ARC system uses a simple "lock-notch" which is automatically engaged when you press the visor down - and to move the visor up/open, you will need to put some pressure on the this lower left part and push up outward and upward... after a few practices, it became easy.
lower diffuser at the bottom of the helmet
Something that I was surprised to see was the diffuser at the bottom of the helmet. Some may think it's some pattern, but I believe these were well thought off to diffuse the air and keep the head stable and not tired in a long ride. The bottom of the visors too, has a notch that resemble an aerodynamic lip that will lend stability. ARC failed to capitalize on these features!

Time to peel the stickers off and lets go for a ride!

Pirelli DIABLO™ ROSSO SCOOTER - Review UPDATE!

Update: December 2021
The Tire has been serving me well in the past 10k km and I would say it is at it's midlife now. Grip is still solid and certain on the corners. Braking confidence is still there, solidly. What I've noticed changes is the wet-grip has somewhat deteriorated, not unexpected but taking corners would require a bit more confidence and common sense (of slowly down). Directional changes is still sharp - bearing in mind that this is a scooter, not a superbike, and it can get clumsy on tight roads and switching lanes between cars.
With another perhaps, 2 years before a tire change, I will see how much more I could push this tire, before deciding if I will stick to the same model, or change to another tire for future easy town commuting no drama ride.
Until then, keep safe!
This review post has been written on March 21, 2019.

Two years ago, I did a review on a pair of Pirelli Angel CiTy that was fixed to my 13 years old underbone motorbike. 2-years on, I have no complains of the rubber's performance in both wet and dry. Every corner and every braking I did on my daily commute is with full confidence that my wheels will stay on the road. As a conclusion to the "long term review" of this tire, it has clocked close to 4000km over the past 2-years. Low mileage considering I only use it for commuting - and still looked new. No compromise on the grip - wet or dry!  Also, my first bike, the Keeway TX200 came with Pirelli Angel Demon as standard. I know how the bike handles with the rubber, and two experiences tells me, Pirelli makes good tires for bikes too!
Made the 110cc bike looked fast
Fast forward 2-years later, I made a decision to purchase a second hand scooter - A Modenas Elegan 250i, which was a direct rebadge from Kymco X-Town 300i. The 250cc variant is only available in Malaysia. I will find time to do a review of this scooter. I had a hard time trying to find real user feedback of this scooter, as most were written by media and sound too good, driving the marketing pitch. Hands up if you agree real user review trumps any other social media influencers or media write up!
Vrroom!

Nice modern curves of a scooter

The X-LED light is to show it's the Kymco X-Town
The Scooter has two different sized tires/rim. 
Recommended Pressure is 28psi and 32psi
The front tire is a 120/80-14, and the back is 150/70-13. This meant the front tire is 96mm in height, and the rear is 105mm in height. A larger wheel provides better control over potholes or uneven road, and smaller wheels has lower rolling resistance (or inertia). The new bike came with Kenda K711 (and front is known as K711F) rubber. 
K711 150/70-13 M/C 64S (M/C is Motorcycle) (approximately RM180 in Czech or average USD75 elsewhere)
With rating of 64S - which meant it has a max load of 280kg (each) and speed rating of 180km/h. Technically more than sufficient to manage the scooter weight+rider+passenger+load. Kenda tires are good from my own experience, and they make great mountain bike tires. However, I do not know of their reputation with scooter tires.
Kenda 711 Front has a middle line running through, while the rear is more sports aggressive looking
As I bought the scooter pre-loved, it has 4000km on the dial. I rode it home from Jenjarom, via SKVE and NKVE - a decent 40km. Tested the tire at legal speed (90kmh and 110kmh) with occasional sprint (80-110km/h) to see where the power and torque comes in (22hp at 7000rpm and 21.7Nm at 6500rpm). One thing I noticed was that cornering took a little bit of confidence, and straight line (along SKVE one section with 10km straight) was not as assured/stable. I am sure some of you that rides two-wheeler will be able to relate to what I just shared. The next day, i headed out to get the tire changed. 
Front tire after 4000km - pitting spotted.

Rear tire after 4000km, looked worn on the middle - likely running on too high pressure 
In Come The Pirelli Diablo™ Rosso

While researching on internet for Malaysian scooter community, i came across many discussion on tire of choice for the Modenas Elegan 250i, particularly when the owner/rider were talking about cornering and straight line capability. Comfort and braking distance were part of discussion as well (since the Elegan 250i doesn't have ABS). 
Great workshop for tire change!
Three brand and model came up; Pirelli Diablo Rosso, Pirelli Angel Scooter and Bridgestone Hoop BO2 (lower profile at 70, none at 80). Pricing wise, Bridgestone being the most expensive at more than RM150 compared to Rosso, and close to 200 more than Angel. However, the Rosso sizing makes it a perfect fit (no compromise on speedometer reading as it's exact sizing). 
Front tire rating at 212kg and rear at 280kg. TL = Tubeless. Both tires is about a year old based on manufacturer's date (WWYY)
Based on feedback from a friend that used to ride TX200, and not riding a NMAX 155, scooter wheel balancing is essential to ensure even wear and stability. Since this will be changed, the shop offered free balancing and installation. No complains there as balancing will run up to RM50 (total) for me separately. 
Rosso front tire - make sure you install it the other rotation around for water dispersion!
The tires cost slightly less than RM500 (for both, can't remember exact pricing but I know the rear was more expensive due to wider width). Once everything was done, i got a reminder from the mechanic to "please do not ride too fast today as the tire still has a wax layer on it". Adding to that, it was raining. Talk about testing the wet performance immediately! Why not???
Wet Performance
3-rain rides over the past 600km since I took ownership of the bike. Confidence from KM 2 of the ride was very evident. I still rode carefully along DUKE highway (journey of 25km) with heavy rain pouring down all the way. Was cautious as I never rode a scooter, so my ability to take corner on this Elegan 250i was not as great as the Motard (TX200) and the underbone (Modenas Kriss). Then it rained heavily about 3 days ago, and yesterday (those God-sent rain were a great respite from the 38degC heat!)
Drizzle starting!
The Rosso lives up to the claim, and the other bikers' feedback, of the tire performance in wet. One of my Twitter correspondence mentioned that the Rosso is "superbike grade". He wasn't far as Rosso is placed as "Sport" range
Angel is placed as "urban" vs Rosso as "Sport"
Dry Handling
A tire that has been performing well in the wet will obviously provide as good, if not better performance on the dry road. As the Elegan 250i is bigger than other scooter, it also weigh close to 200kg - it was very stable at all speed, including manouvering in traffic and on highway. Having a responsive tire helps in changing of direction. When I rode the Kenda K711, changes in direction on highway was slower - or there is a lag with steering response. At speed of 110kmh, everything else is slow (speed is relative), I remember having to change direction to avoid a pothole (on a highway!), and that milisecond split was critical. However, on the Rosso, changes of direction was way more responsive - almost that milisecond counts when avoiding potholes. I hope I am making sense here. 
correct installation of the front tire is important. As shown in the photo above, the tread/rotation is reverse vs the rear. Make sure your tire mechanic/technician knows what they are doing and do not let them convince you (to put it per rotation on sidewall)
Cornering
Due to the construction and feature of Rosso, cornering on the scooter was safe and sure. Infact, it was fun, and the only thing between the lower part of the scooter frame and the road is the size of your balls. Leaning in on the scooter, and with the Rosso on was significantly different when I compared it against the Kenda. On the former, i felt the tire was losing grip as I exit the highway interchange at 80kmh (to a toll plaza), where else the Rosso allows me to take the same corner confidently. Perhaps, it is also the confidence one has that the (newer) tire will do what it does.
The Rosso from back - looked aggressive and changes how the bike look instantly
Tire Pressure
The recommended pressure is 28front and 32 rear for one rider. The tire shop recommended to me both to be running at 32psi for the Rosso. After tweaking it for a week, running it at 32-34, and 32-33, the sweet spot for me was 32-33 where the comfort and handling were optimised for my weight (72kg), and with a passenger (max 55kg). Any lesser the scooter has a drag, and any higher, the ride became too harsh and bumpy. Bare in mind that tire will also heat up due to rolling resistance, and it will increase the pressure by up to . 
Tire rotation, and marking on the sidewall
The Rosso was introduced in January 2017, and it replaces the older scooter tires with more improvement (H-rated to S-rated) and compound
