Stock on my 21R I think is 110 front and 150 rear?

Will a 120 fit on the front and a 160 on the rear?

Anyone run this combination?

I had ask this question before, the answer I got from Matt at Tyga on the front tire was he had tried a 120 and ran slower lap times. But yes they will fit.

Thats cool, if they will physically fit without any rubbing on forks / mudguard / swingarm etc... I might give them a try.

Just out of interest, if you do run non-stock size tyre's on your 16/18/21/28, could you post up size's, and if you had any trouble.

Cheers

The rims will take the 120 / 160 combo, which is good as the 400's all use those, but it will tend to slow things down a bit, and rear clearance is pretty tight.

At least you can get hold of racing wets though.

Cheers Dave, good to know they will actually fit.

I was thinking more along the lines of slicks.

i had a 120 on the front and it really stunk, ruined the handling that NSR's are all about.

Really?!

Well, my current front is a 110 and does not need replacing just yet, but the back looks quite 'used' so I'm going to replce that no matter, so I think I'll try a 160 in there.

I have put a 120 on my mc-18 I think it screws up the profile of the tire. The NSR wheel is not wide enough for the 120. I went back to 110. You should be able to find good tires in a 110 front and 150 rear. I have the Michelin pilot power race h2 on my mc-18 I used it at a trackday great tires. I think Michelin has up graded this tire to the new dual compound tires. If you want slicks you need to contact a race tire distrbuter as most shops can't sell slick (in the States) They can also recomend tires that will fit you rim width.

On my mc-21 that I have not taken to the track yet it will be running a 120 front 160 rear. But it has a CBR600 front wheel which is wider than the stock NSR wheel. I Guess i should take both bikes a see what the diffrence is
Hope this helps

not me i run a 150 on the back of my CBR NC29

like mr Honda said to, after all i think he probably spent a bit of cash working out what tyre size was best

Like Monkey says, Hoonda knows what works!

A bigger tyre squeezed on to the NSR rims can actually have a smaller "footprint", and consequently less grip, than the correct size tyre.

Stock fitment is 110/70x17 and 150/60x17, and I wouldn't personally ever change that, it simply works too well.

The exception to the rule is if you fit slicks. Apparently there isn't an equivellant size to the 110/150 in a slick, they are slighly wider, but if you are at the level where you are allowed to use/can exploit the use of slicks, then you'll probably be racing an RS anyway!
