| 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. |
