I just finished installing the Racetech springs .75kg and a 2001 GSXR600 shock today. Can I just say WOW, what a difference from stock.  The bike feels more stable, planted and I feel more in control.  After the work was done I couldnt help myself but take it on a local dirt road for an evaluation and I am happy with the results.  The fork springs are much more responsive and the spring quality is evident. The rear shock actually  has dampening characteristics including  adjustability and the spring weights are very balanced from front to rear.  The only difficult part is cutting part of the plastic fender to fit the shock, be careful  there is a wire that is above where you need to cut.

Fork oil 10wt 130mm from top, Race Tech .75kg constant rate springs, 15mm preload
2001 GSXR600 Shock that raised the seat by 3/4 inch
 I weigh 240 pounds and only ride paved, dirt and gravel roads.
 There are a few instructional videos on YouTube

Nice work, sounds like what I need. What spring rate are folks using with the GSXR 750 shock? Is it stock length or longer? Im 230 with gear, figure 60 lbs of added luggage.

Ignorance is Bliss

You are not "UPGRADING ON THE CHEAP" you are hacking your bike by shot gunning some new and used parts at it, and praying it's better.

Your Spring rate for 260lbs is too low at .95kg/mm and I'm guessing Race Tech does not have one ..........But Promoto, Wilbers and Hyper Pro does.

Really? A Used Track Bike Shock on a Sit Up bike with 27degree caster and a 110 trail?  Whats the Spring Rate of that Shock?  Whats the Seat height and did you have the shock Dyno tested? Or again, spray and pray?

Again, you could have spent 500 bucks and bought the correct springs and a shock with adj. Pre load, and rebound that would have been a great set up, and a well performng suspension.
