We let loose the Ohlins technicians from Harris Performance on our long term test GSX-R1000. We wanted to see how much they could improve the stock suspension with the aid of a tape measure and the tools you'll find in your bike's toolkit.
The result of their simple adjustments is a bike that feels immediately more compliant and which Harris's Dominic Ferrar reckons will be less likely to run wide. We'll be testing that theory at Rockingham on Wednesday night (August 25). I rode the same track on the same bike last Wednesday - pre suspension adjustment - so it should prove the perfect comparison.

Ferrar warns that the tolerances on mass produced suspension mean the precise adjustments we quote here won't work for everyone (Ohlins offer more precisison, he insists). But they should serve as a useful base.
Static sag - Front: Ferrar started by setting the static sag. Ideally this should be 28-30mm on the front. But even with the preload wound right off the GSX-R still had 26mm.
Static sag - Rear: The rear sag was measured at 18mm - way out. It should be closer to 10-12mm. About 4mm of pre-load was wound on to reduce static sag to 11mm.
Front preload, compression and rebound: Our GSX-Rs front came to us with six clicks of rebound, two turns of preload and 10 clicks of compression. Ferrar changed these to five clicks of rebound, 0 turns of preload (wound right off) and eight clicks of compression.
Rear preload, compression and rebound: Our rear preload was wound on by about 4mm to give 11mm of static sag. Compression was left as it was (eight clicks on) while rebound was changed from seven clicks to nine clicks.
