Question Help on Tire Upgrade for Unicorn!!

Motorcycle Gurus,

I'm planning to change the tires for my Unicorn . I've decided on the rear as Michelin M45 100/90 on the rear. Should I go for the same M45 in the front or stick with the MRF Zapper !! Please Help!

Thanks in Advance
Ramesh

as far as i know, your stock tyre on the front from MRF is 2.75-18 ZAPPER FS. You can install this. Other than this if you want to install the same 100/90 then you can do that too, but you need to check first if there is space between your forks to install the tyre. My dio also can fit 100/90 on the rear and 90/100 on the front, so i changed the front to a 100/90 too because there was about 1inch of space on either side between the tyre and fork so a 100/90 would typically leave about half an inch of space which is adequate for the tyre to function and it wont rub against the fork.

hope this helps.

Michelin M45 is available as 3.00x18, 3.25x18, etc. For you, if you can find it, go for the 3.50x18 for rear. If you are changing the front, you may as well go in for M45.

What's the need to upgrade? Stock sizes work well enough.

Brands depend upon how deep your pockets go.

Michelling M45 can be used on the front and rear both?? I thought it was only for the rear. Has Michelin indicated somehwere that it can be used as a front tyre too?

Ah... the question again. Yes, it can be used in front and rear. Make sure the arrow is towards the direction of forward motion.

I dont think it says that on the tyre. Michelin does say M45 front/rear on its websites.

Putting thicker tyres will impact the fuel efficiency, remember slimmer tyres means lesser contact surface with road and hence lesser friction.
Remember friction is inversely proportional to Fuel efficiency.
If looks are important then you can go for a tubeless as it is on the new GS150R.

M45 in 3.00x18 can be used in front AND back. There are clear directions on the tyre to indicate the direction in which the tyre should rotate if it is in the front and if it is in the back.

3.00x18 will become too thin.

@Punter --- Please dont do that! You will lose out on the awesomeness of that bike. Stick to stock size. Dont upsize.

you guys know what, its time that i did the tyre upgrade on my bike too, but the sizes i want are not available at all man,

i wanted 2.75X18 michelin for the front and 3.25X18 michelin or 90/90 - R18 for the rear, for the bike but not one dealer has it in Hyderabad.

these are the best tyre sizes for this bike man from my 2 year experience with this machine.

i have been previously running 120/80-R18 zapper Q and i ended up with premature clutch plates wear and tear, if any one has any leads to the michelin 2 wheeler tyre dealer please help me with this.


also if there are any shops that i visit for these tyres in Bangalore please let me know i planning a trip to Bangalore month guys, Bangy tbhpians please give me some pointers mates.
