The CB650F’s (EURO4 compliant) engine now develops 67kW @ 11,000rpm. This is down to a new intake and exhaust system with shorter air intake funnels linked to a down-flow airbox. Together with a 4-1 exhaust, with a larger muffler outlet, you can hear the power as well as feel it.
A body of steel
The CB650F is built around a steel diamond frame, which incorporates twin 64mm x 30mm elliptical spars. A rigid balance specifically tuned to deliver delightful handling with high levels of feedback. Rake is set at 25.5° and trail is 101mm for good straight-line stability. The wheelbase is 1,450mm – short and sweet – for excellent turn-in performance.
