I told them I just started racing it, so wasn't exactly a front runner but even to me the bike was more than a bit skittish under braking and they advised one of their 20mm piston kits could be fitted and they could respring it to suit me. They said they'd not done an NSR250 before but that it'd just be a normal Showa Honda fork and asked me what the bike weighed and what I weighed kitted up. Reckoned they could "transform the handling".
Then they said (about the rear) the Showa (remote res) unit is basically very good but lacks adjustability, he said they could refresh and rebuild it (it had a leak) for about £70 or supply an Ohlins one at the price I mentioned above but said "it's not cheap, how fast are you? That stock shock can win club races easily". Regarding fitting shocks from CBR600's and the like they said dont just fit a shock from a bigger bike as race bikes don't have hard suspension, they have effective suspension, it's not the same thing.
So that's what I had done, the bill was a tad over £500 and I've not twiddled anything, just bolted it on, they reckoned it would be close to spot on as they set it. Made a massive difference under braking, in corners it just goes where you look and even with the engine getting tired now (53 bhp on the dyno the week before last, that's 10+bhp down on most of the grid, maybe 20 or more down on the fast 400's) I was able to get on the pace of the back of the "chase pack" and lapped a couple of seconds a lap quicker (round a 60 second lap) than guys I struggled to beat last year.
I was going to ask one of these trackday suspension experts to help set it up and when it does something other than exactly what I ask I might do.
Until then it's better, far far better than me
