I've been trying to source an ND5 manual from Japan for years, but when they come up they are just insane money... £100+, plus local fees/shipping, plus agent fees, plus international shipping, and it's just to much!

Having said that, depending on your project, I think you would be much better off with an '87 MC16 or 88 MC18 R2/4J swingarm. The ND5 stuff is extremely rare and hard to come by.

The ND5 is more like NS250R. The NF5 is in some ways similar to NSR250R. The NX5 & NXA are totally different. (Drive was swapped to the RHS from NX5 onwards.)

Bear in mind the RS uses a different shock linkage arrangement to the NSR.

Hey, thanks for the reply.

Having done some more research on potential parts since the swingarm itself is quite cheap, I think that some parts could be sourced from other bikes.

For the chain adjusters, I think that they just re-used parts from some of their production bikes of the same era, probably the same for the rear axle. For the linkage, I believe that the linkage from MC28 NSR250 would fit since that swingarm also has "ears" on it instead of a bushing. Chain sliders could probably be custom-made by bending a thick piece of plastic.

Not entirely sure about the brakes, but I think that I read that one of the RS250 bikes had the rear brakes from one of the Honda scooters, so there's a chance of it being similar to the chain slider situation. But that's for the future since I haven't decided on what rear wheel I will use, wouldld like a 17" wheel (I think that there was one in the NF5 manual), but most of them are 18".

As for the manuals, I only found a reproduction manual on ebay, but it's only $33.

Also have you looked through these Japanese pages for useful info?
