Can I put a 120/17 70 on an R6?
 

Title says it all. I have a spare tire laying around and want to know if I can give it to my bro-in-law to put on his R6...

you mean a 120/70-17? That would be the stock front tire size... Probably a 180/50-17 rear.

No I just typed it wrong. Its the front tire, 120/60 17 is what I have.....120/70 17 is stock. My bad.

A /60 would work, you could adjust the suspension to work with it, but I don't recommend it.

Check the fender clearence too, the 120/70 is a tad taller sidewall but it shouldn't be an issue if it has stock fenders.

edit: nevermind, clearence won't be an issue going TO a 120/60

120/60 sucks. I rode on a 65 on a few bikes, HATED IT. felt like trying to steer a lead brick.

120/70 will fit pretty much any modern motorcycle made in the last 23 years if it has a 3.0-3.5"x17 front rim.

60 series would be absolute junk on an R6

I know the typo has already been pointed out, but now I can't stop picturing an R6 with a 70" wheel on the front. :lol:

It will match his bicycle.

It will never feel right. You could measure from the axle to the ground with the 70 series and then try and lower the forks in the tripple clamps to restore ride height but it would screw with your rake and trail numbers enough that it would feel like crap. My ZX6R came stocke with a 65 series front and I had to adjust the other way to install a 70 series...
