I have a 92 zxr250c & if you want a more race oriented bike get one of these or a cbr250rr, dont bother with the single r unless its really good value they are more a nanna's bike, although still better than a across or the like! The zxr feels slightly bigger so if you a bigger lad maybe better. As for the power of a big ie: litre class bike revhead is right, i had a ride or 2 on a mates cbr900 a couple of days ago & the first ride just blew me away with how much acceleration they have, & how easy to whellie. To give you an idea, 2nd gear @ 100km's flick the clutch & feed the power on & up she comes, it's just awesome fun & this is a 94 model so would be down a little on power compared to Revheads929 or a R1!
