rear OHlins spring
Has anyone had a professional set up to their suspension, and if so by whom, and can they tell me the numbers on the spring, and their weight?

Try Kais suspension in Atherton, or maybe Maxton, plus the other usual suspects... JHP, Harris, Techmoto, Cornerspeed, Sigma etc

I know where the companies are, i was enquiring specifically about the rear spring.
reason being, at jhp yesterday john said i needed to fit a rear spring of 7.5. this has i believe 75 on it. Well i have one of these, if its the one i can save myself £50+.

Andy b - not sure of your experience so I may be teaching granny to suck eggs etc....but Take care with advice from others. Make sure you set the bike up the way it suits you - Not John Hacket or the way neil Hodge has his set-up.

I fitted a heavier spring on Johns recomendation....less preload tension on a heavier spring is supposed to giving a more progressive ride response and better adjustability.

I hated the choppy ride, I spent months trying diferent adjustments with preload, rebound and compression. Eventually I went back to the standard spring.

Its a bit like the front steering head angle - some people will say ohh no leave it alone - nobody races with the steeper head adjustment. I love it, quicker turning without the rear of the bike high in the air gives me the confidence I need to get the power down early without the fear of highsiding.

We all ride a bit differenly.

Its a mono, but had hyperpro rear spring when i got it. I have aquired a 75 rear ohlins spring which i suspect is a bip one, a mono being a 65.

Cooking on gas now, got a ride height tool. adjusted my 75 spring to show 25mm thread. this gives a total sag of 30mm on the rear.

distance to datum line is 230mm for ride height. Could do with a bit more perhaps?

we shall see.

My rear Ohlins has a 6.4Kg/mm spring fitted to it. My unit is off of a SPS and therefore meant for solo riding. Suits me on the race track with my 11 1/2 stone weight. If using a longer arm you will need a stiffer spring, if your using mag wheels you could get away with a lighter spring. Speeds envolved and types of surface will also help determine spring rating, as will the amount of available shock travel.
