Lowest "safe" engine RPM for the ER6 / Ninja 650 / Versys 650 ?
Hi
I have a 1st gen ER6 since a few days, I really like this bike, with a lot of low-end torque, but I'm curious about how low in RPM I can ride it ?
I feel I can cruise, and accelerate smoothly (just a slight throttle) without the engine knocking at 2000-2500rpm for the 1st/2nd gear and 2500-3000rpm for the 3-6th (on flat road), but it is fine for the engine in the long-term ? I have a relaxed riding and try to avoid making too much noise in city, plus fuel economy, so I don't feel like cruising at 5000rpm...
Of course, if I feel that the engine is "unhappy" or force too much I drop a gear.
Thanks for your advices ;)
