Ok.....I gotta ask "why?"....
The Big Ruck is already using a 3 piston nissin on the front, and drum on the rear....I'm not quite getting what you're driving at.
Someplace in here somebody has swapped the rear disk set-up from a Reflex on to the BR
It was me.
Rear swingarm, rear wheel with disc, rear caliper, muffler, exhaust head pipe. All this stuff needed from reflex.
Also lot of fuck with replacement rear brake pipe to steel braided brake hose.
It was worth it?
Another way - try to find Honda Foresight 250 SE. SE version have rear disc brake too. With FES SE replacement, you need only rear wheel and brake caliper. Also need to drill swingarm to inctall caliper. There is small holes witch should be drilled on BR swingarm.
True jedi way - try to find Piaggio x9 250 (With Honda engine)
. You will get the front 14" wheel, with double disk brake, and rear 13" single disk wheel. Brake system by Brembo. Fucking lot of fuck with swap. But very interesting.
God mode - Vince way.
