From the price of both Michelin and Pirelli, should be good tires. At first I looked at Corsa but Corsa doesn't have the exact size for my rear tire. Then I saw Michelin Pilot Street 2 just a tat more expensive then Corsa. Review of the tire is good, so I get it. But Shopee delivery is slow tho.

I saw some Pirelli tires on Shopee but the price is like PREMIUM, not within budget tho, anyone used Pirelli before? How it compare to Michelin and Corsa and any other brands?

which Pirelli?

am on pirelli supercorsas..... very good tire but wasted on me. the compound is very sticky i have to slowly brush off the stones sticking to the tire everytime i take the bike out.

Depend where you're, is cheaper to go get it at the shop actually.
Usually price include installation (with balancing).

sdeemithose are "R" tyres so more expensive

I went to collect my bike today at Shah Alam. But it rained when I’m half way home. Need to hide under bridge for half an hour. Luckily I already got my Taichi jacket and off brand gloves, also HJC C10.

Anyone know how to reduce the vibration at the grip? The vibration is killing me ngl. Does a pair of good gloves help?

Since its a used bike it could be because of wear and tear.
Check if handlebar screws are properly tightened.
Handlebar grip might also need to be replaced something with softer compound like Domino A010.
Gloves with thick fabric at the palm and finger area could help too.

Other factor could be that you are gripping the handlebar too tight. This is common to new rider.
Loosen the grip and make it that you can turn the handlebar with just your fingertips.
Relax your shoulders so that you arent pressuring your wrist.

R25 doesn't vibrate from my experience

Only till yesterday I realised the rear tire got changed at Imotorbike was flat. And I rode it all the way from shah Alam to Seremban. Luckily I didn’t die from the totally flat rear tire.

I just changed the coolant, air filter (old one dirty like my butthole), front and rear brake pads, and rcb grips. Also adjusted the clutch free play

Fairing is pain in the ass.

Vibration need to see improve or not on next ride.

sounds good, hope you enjoy riding the bike
