Great looking bike you have there...

Couple questions

what's length on the rear shocks?
are those 17" wheels?

Here are a few photos. The first 3 are of my YZF, it is my commuter.







This is my KZ, triples and gas cap, clutch and ignition covers, Zephyr swingarm, frame bracing, and ZRX shocks,and YZF600 forks and monoblock calipers with the stock KZ wheel.















The last photo is a friends STD. I did the CNC parts and helped with the design work.

Are there pics of your bikes?

I was going to recommend a lower seat but it looks like you did that already.

You can buy shorter shocks or find a serviceable shock like the ZRX shocks and install a limiter. It's basically a disc that fits in between the shock piston and body of the shock limiting how far it expands. I've made them for MX shocks out of polyethlene rod.

I'm new for this site and I read all of this project. Cool stuff! So I try some parts on my KZ650LTD. It is GSXR front end, bolt rite on like its made for it. In back some Ninja swing arm and it need bushing bore bolt and about 1/4" spacers on sides, between frame and swing arm. Than going to weld tabs on sides for two shocks which going to be from ZRX.

Looking good!

Gas tank of Yamaha XS750 and seat I just steak on of different project, I thinking mo Kawasaki classic race tail or find one more gas tank and cut of part of it and use for stub.


Any suggestions, word of advise and criticism welcome!

Thank you guys!

Hello, Voxa_33, and WELCOME to KZrider!

But your interesting project's likely to get lost mingled here in D.Nel928's thread.

Would recommend starting a new topic for your KZ650LTD, which should elicit more and better responses.

Good Fortune!

patton you need to take this bike to the chrome shop.

I did install a ZRX swingarm and shocks but other than that the frame is pretty stock. The bike handles really well and is not flexy. I ride it really hard in the twisties and have not had a problem with it. Now if I was going to race the bike on a track I would probably brace it due to the higher speeds. On the street and at street speeds I would say no bracing needed. Now I don't know if the KZ650 frame is any stiffer than an early KZ900.

That gpz frame is far stronger than a stock kz900 frame,especially in the backbone and steering head area. :laugh:
