nice write up. i think that dyno is rather optimistic though

Actually. our runs 5% under most others....the stock gsxr ran long 2" headers of unequal length, the Bimota uses thinwall 2 3/8 equal length short system with collector (4-1-2)with much less restrictive dual mufflers and proper jetting and advance curve; the airbox is a huge thing with long tracts and a very large opening and came with a K&N unit, those changes alone would give a 10-12% bounce over the stock motor, which was very lean and had an advance curve set for emissions, not power to begin with.

Suzuki rated the 97 1100 156hp (most likely that was at the crank).

Our techs stock 98 (essentially the same bike as the 97 GSXR) puts down 141 HP at the RW on our dyno and the A/F curve is all over the place; lean on the bottom and fat on the top. The Bimota's is much flatter and running about 14-15/1 at full throttle.

Given the changes that Bimota did, that 158 is feasible, if not likely.

I don't think I could even get on that bike. I have trouble with the ergos of your DB4. Sounds like this thing would kill me.
