With the bandit 600 wheel what year did you use? And does the sprocket line up well?

also if this other swing arm is wide enough would the gsxr wheel have sprocket alignment issues?

I think the wheel is a 2001 (just look for one with straight spokes rather than angled which is the earlier wheel) the sprocket carrier will require machining and you will need an off set front sprocket. I think this is the best option with the GS Swingarm if you are running "twin shocks" the GSXR swingarm is not symmetrical so brings additional challenges with shock alignment (I am using mono shock with the GSXR swing arm)

I have done many wheel and swing are swaps and anything can be made to fit anything else.
You may have to change wheel bearings etc to allow the use of a smaller spindle to fit the arm.
A 5.5" rim  with 180 tyre will fit the frame but will probably be too wide for the GS swingarm so you may either have to go for a narrower rim or a wider swingarm.

I don't disagree with you Zed, however unless you have access and the skills to do your own machining (which obviously you do) sometimes simple is best. To use the GSXR wheel in the GS swingarm the wheel etc would need to be adapted to come down 10mm on the axle diameter (not impossible) but if he is determined to run the big wheel then a complete GSXR600k1 back end would make sense, with the exception of shock mounts the swingarm is almost bolt in. The KZ inner races and centre tube fit perfectly inside the GSXR inner races and support tube, all that is needed is a 1mm spacer washer either side. Even the stock GSXR dust seals fit perfectly

 

I think you will have issues using a GSXR wheel. The later GSXR (K model on) has a bigger diameter hollow axle which will be too big for the GS swingarm (also you may run into alignment issues with a 180 tyre) Your options would probably be a GSXR swingarm as I have used or a 600 Bandit wheel with a 160 tyre (which I am also using) which has the smaller diameter axle. Also I am using the 600 Bandit brake and sprocket carrier

 

Back to the UK this month for Rob’s (Zed1015) Z900 powered “1 of 1” all business “tarmac terrorist”. This monster has nothing that isn’t strictly needed for the purpose of “hauling ass” including lights (it has a brake light only which is the minimum requirement for a “day time” MOT here in the UK)So from the top, heavily modified 750 Zephyr frame, ZX10R front end (with the fork internals reworked to add 32mm to the length), GSXR swing arm with a Z750 wheel, R1 callipers all round and a Suzuki rear shock. So with the chassis boxed off let’s move on to the motor which started as a Z900 which has been bored to 1015 (no surprise there) welded Z1000A crank, Z1000 MKII transmission, ported Z1 head, fast road cams, custom exhaust and 26mm carbs which Rob has bored to 29.5mm. The engine is solid mounted as it now also fills the role of being a “stressed member” in the minimalist frame. On the topic of minimalist the bike is “kick” start only as the starter and generator have been replaced with a “race” generator and 8ah battery in the tail piece (Rob did experiment with a “self generating” race ignition in place of the generator but unfortunately the “kick start” doesn’t spin the motor fast enough to allow it to start) which ended up being a very expensive piece of R&D !! the bike also runs a high level oil cooler in place of the headlight. Rob has also build a one off clutch actuator to mount on the “outrigger” in place of a sprocket cover.This bike is completely self built with some fantastic engineering work but for me some of the most impressive workmanship is the all alloy bodywork (only the best fabricators can work to a high enough standard to run their sheet-metal work raw)I would recommend taking a look at the full build thread on this link Zed 900 road racer - Updated with fixed links. - Z1OwnersClub GB
