The next level

Ok so the time has come for me to step up to the next level with the electric motorcycle builds.  The RG has been a great bike even though I keep pulling it apart to do other things. However the size of the frame limits what I can do with this build.  Little room for batteries and even less for a larger motor.

I have decided that rather than re-arrange the bike again trying to squeeze 64ah of batteries at 72 volts, I would upscale the bike instead.  This means I can now go from a 5kWh pack to a 9kWh pack and 96 volts nominal.

So here is the plan.  I have a 2002 Yamaha YZF R1 rolling chassis much like this one but without the motor and stuff.


Next get the help of an awesome fabricator, Damian Butcher from Driftech, and work out what we can do.  I was able to purchase a Motenergy ME0913 and Kelly 120v 400amp controller from Al at Electric Car Conversion Blog, so Damian and I started to look for design inspiration.  Looking around on the internet and having some discussions we decided that the build should be GULF Petroleum colours.  Not only do they look good but the irony of a defunct oil companies colours on a new electric bike is something we could not deny.

Searching for inspiration I found this awesome Ducati owned by sfarchi on


This will be at least a two stage build.  The first stage will use the existing frame and a tester battery pack to confirm the performance and weight distribution.  This stage will utilise the current frame with little or no modifications.

Stage two will see a custom build trellis frame with some custom body work.  The subframe will be aggressively short and the bike will be as naked as sfarchi’s above.

E1 build 734So here we are with a rolling chassis short sub frame and motor mount.

Stay tuned.
