I NEED A LOAN FOR NEW TOY!

When should we expect a retro fit kit for an R3 ?

How much power does the current setup consume ?

Can you imagine a 265 carpenter setup with 1% loss drive train .

We will let @Claviger sort that out with his dyno when available....................

That would put you at over 300hp to the rear tire.

I’d actually like to watch that system under load...I’m not sure if it can handle the torque that needs to be applied to actually drive the wheel. Materials seem a little thin!

The rear cogs look to be aluminum. It's a race bike so you would be replacing the cog set often. but worth it

Now we're talking..

Beautiful proof of concept. There are still serious hurdles before it’s ready for prime time, but what a phenomenal demonstration of what a group of engineers can come up with when not constrained by budget.

First hurdle... variable geometry driveshaft to allow for suspension integration and frame flex.

Given it needs to be enclosed - that will be a ruddy big bevel box.

Beside that, they have not worked out a method of changing gears while moving. Currently the bike has to be stopped and adjusted/pulled apart to change gears. That would not be useful on a m/c, we had similar systems with leather belts and pulleys on veteran m/c's. They then progressed to 3 speed hub gear boxes like Sturmey Archer which ceased use in m/c's before WW2 and kept in mainstream use on GP bicycles until the late 1970's.

Just a big egg beater really.

The gains of the system are already in our shaft drive and longitudinal engine layout with one less power direction transfer than many shaft equipped across the frame 4's or V2's. Once you add necessary uni joints to handle suspension movement etc. or change direction you add losses.

Not so - The gears change wirelessly. It's only when you want to change overall ratios that you need to stop and swap the shaft.
As for flexing a good start would be a proper CV joint in the swingarm pivot rather than a universal but precise positioning would be a must. BUT - materials selection for a 200ft-lb power feed would be crucial.
