Ohlins Brutale rear spring for sale (fits sachs shock), and the original blue 2004 Brutale rear spring (Sachs).
I bought the Ohlins to replace the stiff blue spring (fits perfect on the Sachs shock, same length), it was a little lighter spring rate but I bought another with a lighter rate than the first Ohlins spring. I'm 155lb and wanted a softer ride.
The Ohlins for sale is model# 01091 31/95 L238 (spring rate is 542lb) I'm thinking it would be good for a 170-200lb rider. $50+shipping
The blue Sachs 2004 spring is rated at 650lb (local spring company rated it) $30+shipping
I'm pretty sure these would fit 2004 up to the last of the first generation Brutale.....
