No trouble with the guards breaking or weakening then?

The JTF520 sits too close to the motor.  Whygostock sells both the belt tension gauge as well as chain conversions.  They also sell a kit that will just give you the sprockets and you can select your own chain locally.

update:

Parts used:
I used sprockets from JT Sprockets
Front sprocket: Suzuki SV650 JTF520.16 with 1.4mm washer, you can use F1537.16 for Kawa KLV 1000 w/o washer
Rear sprocket: Hyosung GT650 R1074.44
Hub: Hyosung GT650 2006 w/o washers between sprocket and hub.
Rear left wheel Spacer from GV650 to make 60mm distance for the GT650 hub, Hyosung part # YL1267
Chain: DID 525VX 118 links (116 may also work) with 118 I'm on 3rd marking counted form swing end.
no need to spent $250 for a kit. I paid for all parts 140 EUR plus DID riveting tool 40 EUR.

The aliment front and rear sprocket is almost perfect, chain to tire clearance is perfect.

Chain covers and swing plastic cover (top and bottom needs some plastic removal) need some work to avoid the chain hitting the covers

don't buy a cheap riveting tool like the one in eBay with 14-13 pieces for about 20 Euro, the metal is too soft.
I used one for DID, cost about 40 Euro and wort the investment.

I know this is an older thread. Looking for advice if anyone was able to find proper spacers while using the GT650 hub?

Does anyone know of another motorcycle that may have a similar axel size as the GV650?

I will consider what the o/p suggested but I would like to know if there is a 60mm spacer for left side of the GV650 and what is the size of the new internal spacer with the GT650 hub? Don't want to torque the axel until these are in place.

Thanks for any advice.

Easy fix to get the correct spacers.
I went to a machine shop and they cut my old inner spacer from the GV650 hub by 24mm (The size of the right side rear spacer pictured below).
Now the inner spacer fits with the GT650 hub and the remainder 24mm I used with the original outter spacer to make the 60mm distance to the hub.






Parts that I used:
Front sprocket:  JT Steel Front Sprocket 17T (525) - JTF1537.17
Rear sprocket: JT Steel Rear Sprocket 44T (525) - JTR1074.44
Hub: 2007 Hyosung GT650 Hub with 2 - 1mm washers between sprocket and hub. ( I wanted even more chain clearance from the chain and rear wheel and the GT650 hub is now flush with the rear sprocket).
To make 60mm distance for the GT650 hub I cut my original GV650 inner space as noted above.
Chain: RK 525 MAX-O O-Ring Chain 118 Links and Master Clip style link

All parts cost me about $250 Canadian (including the GT650 hub).
My Hyosung dealer tried to talk me out of doing the chain conversion and spend over $1000 for a new belt and pulleys.
I recommend the chain conversion for multiple reasons.

Pros:
Cheaper parts when your chain or sprockets wear out
More accessible parts if you break down while riding around North America
My belt drive had an annoying squealing noise and the chain conversion eliminated it.
You can play with different front sprocket sizes to change your gear ratio
No special belt tension gauge required anymore and it's much easier to set you chain tension.
and finally I find that I like the way the bike handles better now.

Cons:
Chains require more maintenance than belts but how hard is it to lube and tighten your chain

Thanks O/P everything works beautifully.  : ;D

Cheers!

For those interested here is a picture of the chain clearance with the GV650 hub and 4 washers between sprocket and hub



Here is the chain clearance with the GT650 hub and no washers (by adding 2 or 3 additional washers you can get about 2mm to 3mm additional space depending on your aftermarket tire.)

Great pics! Makes it clear what you mean by the result of adding spacers.
