Hey everyone, just figured I’d share! I purchased a set of brand new Pirelli Tires for my 2007 GSXR 1K.


These are the newest Pirelli Diablo Rosso IV’s

Rear= 200/60/17
Front= 120/70/17

The rear just barely clears the plastic fender.

Great tires so far! I started out at pretty high 42 PSI front and rear, and I am dropping PSI from there. This is just a stock street/daily commuter bike.

Just figured I’d share. I couldn’t find anyone running these tires in this size. But they are really amazing so far. The bike just falls in to turns so easily. It almost feels like your leaning on glass, and it just takes minimal effort. Apparently this size is a half circle also. Anyways, they have provided some confidence over my old tires that’s for sure. my last tires were Dunlop Q4’s, and they were down too fast for my taste.… I prefer a multi compound tire, that wears less in the center.

Nice looking K7! Looks well kept up.

I thought the Diablo Rosso's had relatively short tread life. I guess we'll find out.

When you put a too large tyre on a too small rim, the tyre is pulled out of shape. In this case pulled "in" by the rim.
The designed shape of the tire, is when it is when it comes out of the mold.
Look for the wear, running off the tyre before it reaches the tire edge.
Thanks for sharing.

Thanks for shearing.

Pirelli states they are designed for a 6” wide rim. And the GSXR 1000 has a 6” wide rear rim. So, it’s honestly a perfect fit, with no deformation. The tire is just much taller than a 190/50/17, so it comes close to that plastic fender is all. Now, if someone tried to fit this on a 600/750 with a 5.5” rim, I could see what you mean by that.


The 200/60/17 tire is just a tiny bit shy of 2” inches taller that a stock 190/50/17 tire.

Thanks! Yes, I love my K7. It is a very clean motorcycle. I have owned it for about 3 years now, and I have done everything possible to keep it as nice as it can be.


As for the Rosso IV’s wear and longevity. They will last much longer than a Dunlop Q4. While the Dunlop Q4 is a really great tire, it’s a no compromise tire. So the rubber is extremely soft on the entire thing. No dual compound Like the Q3+. The Q4 is just an extreme soft and extreme grip throughout. So, we are talking like 800-1000 miles for the rear Q4 and around 2,000-3,000 miles for the front.

Final drive ratio has changed, your gearing will be higher now. With slower acceleration.
Something like 1 ( one ) tooth less, on the rear sprocket.
Gearing commander can calculate this.

Wow ! Just finished some laps on my new tires.
Dunlop KR 106 120/70 MS3 (343) intermediate and KR 451 200/60 (129) intermediate
Huge difference, which was expected, but took me by surprise. Having to lift my knee up to stop it from dragging on every corner.
Don't even worry about braking into turns. 🤣
Question, I will start a new thread, The 200/60 has changed my gearing a lot. Feels like 1 tooth (up) on the front sprocket. I needed to ride one gear lower, which is not ideal.
My best guess is go from 16 / 43 to 16 / 46.
