Hi neo,
I got a trp for my sherco, in short terms it transformed my bike,i run a heavy spring for it as i 95kg, The reason i replaced the olle was to save time and money on constant rebuilds of the olle , the shock is worth its weight in gold, which isnt much coz they weight less than std. With the adjustment and the progressive damping within the interntals its so much easier to dail the bike in.
The spring n shock was i think about $600 au and i got it from kal at kd moto trials in brissy, i spoke to don murray in canberra and a replacement olle was about 450, so if you want to know more hitme up here or on trials oz, tell kal ..... lyndon sent you he might deal on the price,
cheers all
