Hi Folks,
Can someone out there enlighten me with their mechanical wisdom? I am getting back into motor cycling so have gone and purchased a 2004 Suzuki GSX250 inline twin. Rides well and is great little machine to get the "feel" of things again but........ I am not used to these high revving engines. To ride at 100kph, in top gear, the engine is pulling about 9000RPM. She redlines at 13000RPM. My query is can these engines run for extended periods at this rev range. My old bike brain can't comprehend this. Would be grateful of any help. P.S. I have no issues spending good money on good oil and regular servicing.
