91 gsxr 750 suspension

[Damienga15de]

Just recieved my s1000rr rear shock today 8.5kg/mm  and have ordered some k-tech front springs 1kg/mm

 

racetech calculator says i need a 9.7 kg/mm shock spring and .99kg/mm fork springs, for my weight, i know the bmw shock is closer to what i need but would it be worth getting a 9.5kg/mm spring for it ?

 

The forks will be rebuilt with anything needed supplied by the local mechanic.

Has anyone a similar setup ? or care to chip in with some advice

I am using the same setup on my GSXR-750RR and GSXR-750J. The front forks are from a YZF R6 03/04 with K-Tech cartridges and spring rate 10 N/mm . Rear shocks are ohlins SU503 (GSXR1000 K5/K6) With spring rate 95 N/mm. Both are racebikes With gsxr 1100 engines and the setup is realy good.

Here's the first part of the puzzle anyway , just have to figure out how to strap up the bike now as iv loaned my engine crane out

You must be a big lad if this is road bike. For reference I'm 92kg in all my kit.  9.5kg/mm fork springs were a little harsh on the road though worked great on the track at he sharp end of the fast group. this was on a '91 7/11 with stock road body work and lights.

That said I am going to try 10kg/mm fork springs on my race bike, as this get's ridden harder and I'm running out of travel and get tramping on corner entry. 

I run 9.5 rears with 30mm extra ride height, this works great.

Yeah it's a road bike , Im 100kg in my birthday suit

Well it's In anyway , some wiring and relays to be moved and everything needs tightened up , 

[Dazzler]

Have you lifted the rear with longer bones or leaving them stock length?

[Damienga15de]

Stock for now , will put risers in eventually  had a little off at the weekend so gonna get fairings sorted after forks are done

Ran out of wire from the starter to the relay to get it mounted behind the fuse box looks like I'm losing my little space for my disc lock

fit a wp battery box and ytx9bs that's what I did to mine its not as deep as a 91 battery box
