Ive got an 04 R6. I need some new tires due to some rash on the front and I dont trust them. I would like to put a 70 on the front. For those who have the 70 on the front what are you running in the back? Also, is there any suspension changes needed? I hear alot about the Pirelli Diablos and I was wondering are these tires mainly for the track or do you guys run these on the streets


Sorry for the Noobness boys.....

I believe they have the pirelli in both compounds, and I personally would not put a different size tire on my bike. I don't want to risk it's handling.

I am still running 208's my second set.

When you go to the 120/70 you have to account for the ride height change that the taller tire will cause. I raised the forks 10mm in the clamps, you can also shim the rear shock to add 10mm of ride height.

If you don't adjust the ride height you increase the rake of the chassis and slow down the steering. Which by the was a 120/70 will turn slower than a 120/60 to begin with.

This mod is excellent and really increases the feel of the front end. You lose that "falling into the corners" feel and the front feels much more planted when leaned over, because there is more rubber on the road.

Not to mention alot more room to make adjustment at big lean angles, I had the stock 120/60 to the edges and it nearly washed out a couple of times with the 120/70 you don't even come close to the edge.

DO THIS MOD YOU WON'T REGRET IT.

THey changed the '05 R6 to a 120/70 and raised the rear ride height for the reasons I discussed above. You won't hurt the handling, you will VASTLY improve it with this mod.

right now im running the perielli diablos, 70 series up front on my '03. if you decide to go from a 60 to a 70 series front tire you will have to adjust the suspension to get the bike back to factory geometry. you have 2 choices:

1) raise the forks above the top triple clamp 8-10mm. most say adjust it 10mm. i tried it and tried another riders suggestion of 8mm. for me it feels better, stable.

2) or you could shim the rear 4.5mm. this is actually easier. all you have to do is get the set of washers that equal 4.5mm and raise the bike. remove the top nut for the rear shock and the swing arm should sag down a bit. just install your washers and put everything back together.

i have no complaints with the diablos and the 70 series tire up front. my next set is probably some diablo corsas or supercorsas.

I tried Pirelli Diablos on my last bike and loved them...now most of my friends ride Diablos...will be gettin them when the stock ones crap out...as far as getting the Diablos or Diablo Corsa...depends on what/how you ride...If you are just an everyday rider i would get the Diablos (great wet weather tire, and still kinda soft for good grip). If you ride hard curves, or go to track, i would get the Diablo Corsa. They are a softer tire, which will wear out faster, and the tread pattern isnt as deep, which will in turn lose some traction in wet riding conditions

I like the d 208s no problems at all
Once you go Michelin, you will toss those 208s so far they'll never be found. They were by far (to me) the worst sport tires I've owned.

I'm not that fond of the D208 either, I think I saw the new bikes come with Michelins. I know some of the ones overseas do, damn lucky foreigners.
