So finally got my bike back together, with new R6 shock (courtesy of Devilsyam) and chain and sprockets. Gotta say, though I've only ridden it in traffic around town, the improvement in handling is immediately obvious. The ride feels firmer without being harsh and choppy, it turns in easier and, for me, gives it a better, more front biased riding position. So good news so far, I'm planning on getting out in the countryside this weekend so it should give me a better idea of how much of an improvement the shock gives. If anyones thinking about upgrading the rear suspension on their bike, give Devilsyam a shout on here, before looking at other more expensive upgrades. The shock kit comes ready to fit, its a straight swap and the finish, very professional. Even if you do get called muppet!
