On neutral, whether clutch engaged or not, vibrates in a way that causes minor pain and numbness in minutes. At 5000 rpm has a much higher vibration peak.
Bought it second hand with 30000 km and the vibration occurs on the entire rpm range, but mostly between 4500-6000.
At 4500 rpm: the seat near the tank vibrates the most. Hip numbness
At 5000 rpm : the handlebar vibrates the most. Hands and wrists numbness
At 6000 rpm: the foot pegs vibrate the most. Ankles numbness.
The model is the Honda cbr 600 rr from 2008. The motorbike was never touched on the engine, everything from stock just regular maintenance: braking fluid, oil and filters are the only things replaced on the bike. Even the brake pads and chain with sprockets are stock (they need to be replaced soon). Spark plugs are factory mounted too. It looks an internal engine decompensation, whether evolved over time or manufacturing flaw. There's no noticeable noise that I can tell.
Any similar situation on guessing about it?
