I just put new pirelli rosso II's on the 650r
just found out i can get them for the 300 in 110 70 17 and 140 70 17
those are skinny
does anyone know if i can fit 120 and 150s on the 300?
i would like the bigger tires as i am a bigger guy and i think the slightly
larger tire will give me more stability. I know i will lose a little nimbleness
which is not a huge deal for me as i like having to push harder to turn etc
makes me feel more solid on the bike
Peanut i think you have already listed as having 120 and 150s on your 300
so hopefully you can help me out here

btw the price i was told is 101 for front and 120 for the rear these guys
hooked me up on my 650 as well so if anyone is looking for rosso II's i got a great dealer!

Yes. They both fit easily.

will it hurt my performance at all. what about clearance under front fender

 

[old3]

No, the bike felt slightly slower to drop in on my Contis but within a few turns it was gone. I swapped back & forth from the OEM tires to the bigger ones chasing the steering head bearing symptoms so I picked it up a few times but it fades immediatly. Your specific tire might be more or less of that difference but I don't think many would even notice it.

The grip goes up exponentially. The front tire had lots of room, rear could go to a 160 but I don't see any benefit to that at this weight/HP.

k yeh I was thinking tge improved grip a 120 70 17 front and 150 70 17 rear would be best. I looked at the specs the bikes are almost the same size and I think this will improve grip like crazy. I know there is a 60 pound weight diff but the 300 is only 20 less hp so shouldnt they have comparable hp to weight

I run these same tires and sizes on my KTM 530 and Husaberg 570 supermoto wheels. Excellent sizes and those bikes weigh 100lbs less with about 15 more HP.

Good to know once my tires wear out I can put some which are a lol wider.

Wouldn't you need new rims for a wider tire?

Nope. I'd advise a wider rear wheel if you went to a 160 but the 150 is commonly used on 4.25" rim, the 300 is 4". not enough to worry about. The 160 on sumoto bikes gets a 5" rim.
