GSXR 5,5" rim conversion.

All right. Then GSXR rear and FJ front sprockets.
It takes ages to find all the parts for my bike

Here this might help. It is the JT catalog.  http://www.jtsprockets.com/catalogue  You can look up any bike mfg and model and it will give you the spec's (chain size, off set, spine pattern for the front sprocket etc,).  I run a 1993 GSXR 38t rear sprocket, fits 530 chain. The GSXR 1100 uses a 525 chain so you need or should use a 750 GSXR rear sprocket but use the JT catalog to double check the sprocket spec's because they made many models of the GSXR world wide.

JT sprockets are widely available from any dealer plus on e bay. Get the steel sprockets. 18/38 or 17/38 works fine. 110 link chain will fit. My chain came standard in the box with 120 links, had to remove 10 links.

Thanks. Unfortunately they don't list any 18 sprockets: http://www.jtsprockets.com/catalogue/sprocket/JTF579-18
You say 17/38 works fine. That way I can keep my original front sprocket.
But I swear I read somewhere on the forum that you need to go up 1 tooth on front sprockets for every 2 on the back sprocket...

Details, details 17t is standard, click the 18t and it will give you part number "JTF579.18"  "JTF579.17" is the 17t FJ sprocket.  Contact JT and they can tell you the availability.

Also check this http://www.ebay.com/itm/PBI-530-Steel-Front-Sprocket-18T-Natural-777-18-/221810585921?hash=item33a4f0f141&vxp=mtr#vi-ilComp

Not to confuse the issue this will work also (it is what I use, except I run 17t now).  You will have to machine/grind off one of the boss's.  It provides a better chain alignment for me.

On the final ratio 17 or 18 is a personal choice.  For me the 18/38 was a bit high. But was the difference a lot ? No.  Both are fine. The front sprockets are easy to change (if you have to correct socket) and not that expensive. And both will adjust fine with your 110 link chain.

Or as Mark already said earlier in the thread, RPM has 18t sprockets in stock.

I will also have the rear sprocket Mark has mentioned in stock this week.

Thanks guys, you rock! I'm a happy camper. I found JT sprocket in European shop.
Looks like R1 '98-13 uses exactly the same front sprocket.

Or as Mark already said earlier in the thread, RPM has 18t sprockets in stock.

Thanks Randy. Unfortunately I have to pass, I could buy a few of them just for the shipping costs from USA to Europe.

[racerrad8]

Must be a smoking deal if you can buy a couple of them for the price of shipping, as shipping is currently only 17 USD for the sprocket from here to Oslo, Norway.

I paid 17 bucks for a new 18 teeth JT Sprockets - sprocket incl. shipment.

BTW, I bought back brake rotor for GSX-R 600,750, 1000 - K6, K7, L1, L3 from 2011 and it fits the GSXR 750 90-95 rim perfectly.
