swingarm, subframe and gearbox weight vfr750 1986

Hi there.

i have taken on a quite big project that is based on the 1986 vfr750.
a friend of mine gave me a frame and and engine that he had planned to build a supermoto of . but he got tired of the project and it was just standing there, so he asked if i wanted to take over. project stupidity

the goal is to have the bike raceready at a curbweight of 125kg , i think i will manage this by using very much leightweight materials, i have lightened the bottom of the airbox with 600 grams =) not much but in the end all the small weightsaves i can make will make me reach my goal =)

the problem i have is that i need to know moore about the weight on the certain parts of the frame. i know that the frame weighs in at 14 kg , but i don't have the subframe and i don't have the swingarm,

and i really need to know the weight of the subframe and the swingarm so that when i buy a new swingarm and build a new subframe don't get parts that are heavier than the original .

one more thing that i have thought of is the gearbox, gearboxes are heavy and i will only need five gears on the track. does anybody know how much the gears weigh ?

The gearbox is built into the case with the engine--it is not a separate unit.

 

i have an 86 vfr700 swing arm on my porch. at least i thought it was a vfr 700 not 750. i can have my wife jump on the wii and weigh it if you still need to know

 

i would be wery greatfull

i know that , but i wan't to know the weight of the gears =)

 

I have an RC24 engine apart, will weigh the gear box tonight.

 

The complete engine weighs 77kg

Front wheel 4.25
Rear wheel 5.0
Pair Front Discs 3kg
pair Forks 7.5kg
Shock 3.5kg
Swing Arm no pivot 3.7kg

Correction: I weighed a bare frame without swing, yokes or bolts and its weighs 10.2kg

 

Wow, a VFR750 supermoto. Sounds like fun!
