My son bought Murdo's 93' ZZR250 so he could ride something now, while we still work on the GSF250 Bandit.. Took it for a test ride and about the only thing I didn't like was the amount of vibration that was coming through the handlebars at anything over about 70kph. Insane amount to the point where my hands were numb and tingling after 15-20 minutes on the bike and my hands didn't return to normal for about 30 to 40 minutes. I realise everyone has a different idea of the feel of vibration in their bikes according to what they are used to.. for me - my VFR has zero vibration unless I am in the upper reaches of the RPM scale. Same for my GSX1400. Both bikes are very smooth. anyway. I set about trying to get rid of the vibration on the ZZR as I knew that if I didn't, then my son would not be wanting to go on long rides - I certainly would not want to ride the bike, so would hardly expect him to. For those interested - the result was extremely successful - hence the following write up.
