Is it just my bike or is all the F2 600s vary low geared my bike at 70MPH runs about 7000RPM Is this normal or is it my sprocket,,I have a 15F 43R Is this the stock size. I hate HWY Riding because my bike runs so hard,or is this normal..

 

The F2 revs to 13 grand so your bike is not running "hard".

It's perfectly normal for this bike.

I'll agree with you that 1st gear is too low even with stock gearing. I would like a much longer first gear personally.

 

My bike is essentially all stock, and in 6th gear and at 70mph, I'm taching 5500 on the dot. You are either not in 6th gear, or your sprockets are not stock.

 

My F2 runs 4800 RPMS at 60mph, that is with stock gearing in 6th gear.
