Hi Nick and Welcome.

You could always put a smaller front sprocket on to give you better acceleration, but it would reduce your top speed and make your engine rev harder at 100kph.

thank you for that what would be the best its doing 9g at 110km now and about how much do they cost also i am looking for a manual as well do you or any one know were i can down load one for a 1990 zzr 250 or were i can buy one cheap thank for your help

the front sprocket is about $20 for a -1 front, but you will have to adjust chain accordingly to suit....the supplement manual tells you how to do most of the stuf (might be for the ex250 but is the same bike!!!) never actually found the original workshop manual for it. just do a google for it

Don't worry too much mate - those pesky 4cyl Hoonda's give us all the shits from time to time ... (specially the 08/09 1000cc variety)

Alternatively , wait till you get your open class licence and trade up to a MUCH faster bike

my opinion.. why bother?

+1

you will find the honda revs longer and will always beat your zzr anyway

My 550 sits on 5k-7k RPM when on 100km/h out of 13k RPM just get a bigger LAMS approved bike IMO

The take off speed of a bike is close to 400km/h if you glue wings to it, it might reduce that speed to about 200km/h.

Fark me!!!! Did anyone tell 12 owners this????? I didn't think Kawasaki was being literal when they said it "flies"
