Anyone here know of the difficulty of putting a TT500 aluminum swingarm on my SR? What about the rear disc stay? Shock length and positioning?
Is this worth the effort to reduce the weight and look cool?

"Craftman" or "Craftnan" in Japan has a very cool boxed aluminum swingarm for the SR, as another option.

Hi,
I searched for a long time trying to find a TT alloy swingarm years ago to fit into my cafe racer, but they are very thin on the ground. I actually collector a few alloy swingarms from other late 80's dirt bike (Kawasaki KX and Suzuki RM) to see if any of them could be modified to fit the SR, but in the end I gave up on the idea as it was just too much work.
The TT500 swingarm should fit straight into the SR fame at the swinarm pivot. A rear caliper mount and shock mounts could easily be welded onto the swingarm and the original shock mounts cut/ground off. I suppose it is all down to how "handy" you are at metal fabrication and welding or if you have access to a good metal fabricator.

Thanks for your replies, I saw one on eBay and it looked pretty good, but I'm looking for a bolt on replacement with no welding needed.
Does the early Yamaha Radian swing arm just bolt in? - with proper shock mounts for the SR and brake stay that will work with the stock wheel and disc brake? Is it constructed from aluminum?
Miker - do you have a link for the swingarm you mentioned?
Thanks ~ Doug

Thanks ~ Doug The Radian arm is pretty much a bolt in... However, it is very likely you will have to make up the correct spacers to fit your stock SR rim into it. Fabbing correctly positioned shock and brake stays as well. Worth it I would say. I have one now ready for my next project. NOTE: The Radian arm is STEEL. G Man |

Hi, Those Craftsman swing arms are very nice aren't they.. I have one of his chain roller kits on my DCM...nice rubber covered roller and a simple device. I replaced his roller axle bolt with one I reckon is a little better, but on the whole very well made stuff. SR  |

About $1100AUD for that swingarm... sheesh. Suppose you get what you pay for.
What difference would it make to handling?

Hi guys, i think youll find that the vintage hotshoe swingarm in the pic above is a copy of a knight swingarm, and the spoked disc rear wheel is probably a barnes flattrack hub. Dirttrackers used disc rear wheels on flattrack frames way back in the early 1970s, long before they became commonplace on other types of bikes. Cheers Franky b.
