Triumph 675 Power: 126.05 HP (92.0 kW)) @ 12600 RPM
Dry weight: 162.0 kg (357.1 pounds)
Weight incl. oil, gas, etc: 184.0 kg (405.7 pounds)
Power/weight ratio: 0.7781 HP/kg

Ducati 848 Power: 134.00 HP (97.8 kW)) @ 10000 RPM
Dry weight: 168.0 kg (370.4 pounds)
Power/weight ratio: 0.7976 HP/kg

Aprilia RSV Mille Power: 130.00 HP (94.9 kW)) @ 9500 RPM
(01-03) Dry weight: 187.0 kg (412.3 pounds)
Power/weight ratio: 0.6952 HP/kg

Aprilia RSVR Power: 141.12 HP (103.0 kW)) @ 10000 RPM
(04+) Dry weight: 189.0 kg (416.7 pounds)
Power/weight ratio: 0.7467 HP/kg


All specs from www.bikez.com using the newest available model. Power/weight numbers show a little different line up than talked about at the meeting. Just throwing out some numbers. Thanks for taking the steps to add this class guys.

I'm extremely skeptical of the 370 lb ducati 848 spec. can someone tell me how a street bike 848 with no oil or gas weighs less than a full on ducati 1098r superbike(which i have a little bit of experience with regarding the weight of) that has no lights, no plastic bodywork.? There's very very little difference in the engines between the 848 and 1098r, they weigh very similar. the crank in the 848 is heavier and the rods are heavier and the pistons are slightly lighter. there might be a 3-4 lb difference between the two. and the 848 comes with a steel subframe.

The MRA can afford some quality scales from intercomp. I still think its time to start using weight as a measurement for the rule book. "stated HP" and weight form manufactures is not a good way to judge the things and group them.
