GS 500 F swingarm widening for a EV conversion
« on: March 24, 2021, 05:36:21 AM »
Hi, I am a proud own a GS500F and I'm trying to make a EV conversion based on it. I have only one problem. The wheels of the GS seem to be way too thin for the amount of torque which my motor produces (about 350Nm peak). Because of that the wheel on which the motor sits (it's a hub motor) has a dropout size of 230mm and I'm planning on putting 220/70 tires on it. So do you know of any way of fitting such a big wheel on the GS? Can I widen the swingarm or maybe replace it with another one from a different bike?
Thanks in advance! :D

Servus,

You can take a Swingarm from the Bandit 1200 and a 6" Wheel from the Hayabusa 1300.

What is the weight of the electric motor? Hub motors may work well in bicycles, but all that unsprung mass won't be good for handling on a powerful motorcycle. In my opinion, you'd be better off mounting it in the frame and using a chain. And it will also solve your wheel problem.

Do you have a link to the motor? Just curious because I'm interested in electric motors. Never built an EV though.

The Triumph Rocket 3 has the highest torque of any production motorcycle - 221Nm peak @ 4000 RPM. And you want to use an electric motor with 350Nm torque?

To put that into perspective, that's more torque than some of the Chevie small block engines.

And you say it's a hub motor?  Your post was a few days too early. You should have waited for April 1.  :nono:
