All the component design is done except for the monocoque bodywork and radiator head tank and bleeder tube. Still a good amount of CAD and analysis to do on the monocoque section before I have moulds made.
B.O.M. is essentially done and so I have a very accurate prediction of the final weight of the bike. As it sits, with oil and water but without fuel, It should be 196 lbs +/- about 2 lbs.
The upper body design is still slightly being tweaker as I said, but it was far enough along to do some rendering/sketching, so here is the 'artist's conception' of the final bike, directly based off the CAD:
Now the hard part begins... and step 1 is I move everything out of my Hermosa Beach beach house and into a proper shop.... |
I totally dig your enthusiasm and this kind of project in general.... but, I don't see how you can keep this thing sub 200 lbs. The Japanese factories, with all their wizardry and money, could only keep production RS250Rs and TZ250s to about 220lbs. And that's dry weight. I'm assuming you have a CR500 motor in there, which is really an ancient, heavy motor. Unless their are replacement cases and head available that are significantly lighter? Also, a 500 single 2-T motor is going to be hella buzzy, and won't last long on tracks with very long straights.
