Hello all, I'm new to the NSR250s. Bought my MC18 about a year ago, but sadly she needs a new crank. Anyways, there's been a little issue that's been bugging me.

I was browsing online, looking at pictures of MC18s and I noticed my bike's swing-arm looks different from the other R5Ks I've seen online. So I'm a little confused by the swing-arm that's currently on my motorcycle. The only history I know about the bike is that it has had it's rear wheel changed to a 17" wheel and aftermarket rearsets (Pop Malossi HRC stamped on them. Doubt they are authentic anyways).

So my questions is what swing-arm is on my R5K? is it a R4Js? or?




Thanks for your time
