I bought a bunch of parts from a guy who was giving up his CBR600 (madness...) including a 3 spoke MT4.5x18 tubeless 3 spoke rim with "Honda", "Enkei" and "34P" on it.Looks like original white paint. It's a rear rim, has the same size rear disc asmy 1988CBR600, and appears tosuit a double-sidedswing arm. (1) Can anyone identifywhatbike would have originally come off? He seemed to think it wouldsuit the CBR600 for racing. The onlyHonda rims I can find of that size were from VR400s, but they are 5 or6 spoke, not 3 spoke. and... (2). If it is good for thrashing (fondly) an old CBR around the track or twisties,what's theright size front rim to match it?

 

Found it! CBR400 RR NC-23 tri-arm.
