Kx60 swingarm swap to crf70

[funke5372]

Ok so here goes guys and gal's I have a 2007 crf70, that I'm building on a budget... While taking some time off of the bigger bikes... My 125 is going into storage and my street bike is being sold, but that's a story for another day. I want to put a kx60 swingarm on it, along with xr80 forks. But have a few questions first and foremost is there a write up or how to on modding the kx60 swinger, I have yet to find a thread and I've searched Google, planet mini, and TT. Secondly could I use an older kx60 swingarm and rear wheel ( the drum brake one) secondly what kind of shock to run I've been looking at the fastace 270mm/260mm shock is this ok or will it chopper it? Thanks for any help!

Would probably be easier to get a rear end off an x4 or similar bike. But if your up for a challenge try the kx60. There so cheap to get you can't go wrong even if it doesn't work

[funke5372]

Well I took your guys advice and I kept my eyes open for an x4 swing arm..... Never found one, but what I did find was a nice 1986 kx60 off of flea bay for cheap. Measuring everything up then fit it in.

The frame spars on the crf were 120 mm end to end, while the distance in between the mx was only 99 mm. I can't remember exactly but I think I cut around 11.5 mm from each side used the crf70 swing arm bushings since they have an o.d. Of 24mm and I.d. Of 10mm and fit perfect in the kx60 swing arm. Then since I used a 84 swing arm everything just bolted up with the use of spacers (washers).

Sorry I couldn't be of more help it is a fairly straight forward swap, just I'm a wee bit anal about the finite details and I will probably do another that's to my expectations

[funke5372]

Also the frame has to be modified (an upper shock mount added ) I used a 10.5 inch fast ace shock. I was trying to do it with out any frame modification but when lining it all up it just wasent feasible.

[funke5372]

That's the finished product, has anyone done there top shock mount different? More reinforcing in that area?
