I don't know the size of the stock ones but you'll probably need to let members know "why" you want to change them. Lower end power? More top end speed?

There is no more top speed.

Stock for the SF is 14/39. I think its just right for MY kind of driving.

Once I went to the 351, I put on a 15 in the front and its smoother at 62 mph.

Interesting. Not what I've read on the 'net.



.

All bikes on the net are faster than in real life except mine. :lol:

I had the stock then went to the 351 with little gain in top end. Then I went to a 15/39 to reduce vibration at cruising speed (62mph) Still no gain in top end. It just runs out of balls. Wind resistance has a lot to do with it.

I could also be I am 200 lbs and have a small windshield.

after putting on the 13T front, I'm much happier. I commute 20 miles a day highway, but enjoy the back roads route more. I'm sill getting 61MPG, but have a TON more fun doing so.

P.S. I'm 6'1 250LBS
