no on the shock mount on the 2017 and up honda is a lot lower than the previous generation. So there is way more space over the shock.speedy1984 wrote: ↑Jan 08 2023 8:22amLooking goodAm i seeing things or have you chopped the centre section of the frame out?

Also stated working on the gear reduction. I welded the bearing support into the chaincase and started making the brakets that go between the swingarm.

Looks good
Do you plan to put steel spacers between the bracket and swingarm? (I see that you left some space there)
I think that can be a good idea, the alu gets a bit soft.
Is it the autput shaft from the bike you use and mount the sprocket on?
Will you be able to use it, or is it just a mockup ?

Re: crf450r 45kw race bike build
Yes there will be another gusset between the two to make it stronger. The shaft is th one from my previous build. It is made from a snowmobile shaft that happen to be the same spline as a ktm sprocket. I will bu using the same part but it will be a new one because it needs to be longer.j bjork wrote: ↑Jan 08 2023 1:14pmLooks good![]()

Re: crf450r 45kw race bike build
finished welding the supports for the bearings and started working on the chain tensioner.
Re: crf450r 45kw race bike build
Delicious welding, I'm jealous 

Re: crf450r 45kw race bike build
Finished the chain tensioner and started working on the battery. Trying to find the best shape for the series and parralel connection.
