Today I had a few things to do.
Delivered a frame, swing arm, brackets and wheels to the powder coater.
Then I dug out the mule (to be the subject of some future project no doubt) to use it to set up another GSXR wheel/brake conversion.
I will be using this braced swing arm so I wanted to see what was required by way of a torque arm for the floating rear caliper. I need to do more checking but it seems it will need a shorty (in yellow) arm that will render the caliper fixed, as the bracing might foul a longer torque arm fixed to the frame just behind the engine.
I will also check brake hose lengths required. The plan is to run a pair of hoses direct to the front calipers as the new front brake m/c has a micro switch built in.
The GSXR wheels allow safe fitment of wider tubeless radial tyres with modern sticky compounds, larger discs, and via CNC-machined adaptors, 4 pot Brembo calipers out front. The weight saving is big, saving around 3kg on the whole front wheel assembly (lighter wheel, no tube, thinner stainless discs), and around 1.5kg on the rear wheel.
This has a knock on effect on the suspension too.
