I dug the Dec 2001 issue of "Sportrider" to compare to the July 2008 issue of "Sportrider". Hopefully they used the same scale to weigh both bikes. Their wet weights of the 2 bikes are:
435 wet for the `01 F4I 98hp, 43 ft lbs torque. Roll on 6th gear 60-80 4.60 sec.
413 wet for the 08 600RR 102 hp 43 ft lbs torque. Roll on 6th gear 60-80 3.72 sec.
In the same time period, the Suz GAINED 18 lbs. The Honda is now 28lbs lighter than the Suz. Hard to believe...
All Dynos are different as are all bikes. Last year the Dyno charts that I saw put 106- 109 as the rear wheel HP of the 07 600RR. Why the discrepency is anyones guess. I rode my friends 01 F4I after putting tires on it last week, and I was surprised how strong it felt. He had a 2 Bros slip on. My 07 is bone stock, with a one tooth SMALLER sprocket on back, making it slightly taller geared than stock. You probably need to ask guys running the 07, and see how well it responds to "tuning".
