Well I have a '98 RRW which is pretty similar to the '97 - I used to get over 50mpg REGARDLESS of how I rode it before I had the dynojet fitted, now I guess I'm in the mid-high 40's. It develops 121bhp at the rear wheel.
Power delivery is fun, enough power & torque in the mid-range for normal-quick riding, but when you go past 7000rpm you unleash hell and it flies!
I've had no reliability issues, but it's still low mileage (14500) but these go on forever, well over 100,000 miles is no problem for these bikes. They are also mechanically pretty simple too - so less to go wrong in the first place, simple to service and maintain as well.
Handling I find excellent, no matter what comes up the bike deals with it, mid-corner bumps etc - the bike just seems to shrug it off. It's a far better bike than I am rider, that's for sure. It loves the twisties!
It took me about a year to 'click' with my bike, which would be my only word of caution - but this is probably just me, lacking confidence after crashing my old bike
I say go for it
, I find my 'Blade to be an excellent bike and would recommend it to anyone looking for a sports bike. They're pretty cheap too at the moment (in the UK at least) so you get a lot for your money. Worst case, even if you hate the bike you'll probably be able to sell it on & get most, if not all of your money back. Good, looked after ones don't cost a lot more than abused ones, so search out a nice one and it'll serve you well.
