6th gear? What for? It only runs 5.7 to 5.8K at 120 mph. As to normal riding (cruising) I shift at lower rpms. Sprot riding I like to stay in the power band 4000-5500 range.
Use the whole range.
My bike in 5th runs about 18mph per 1k rpm, giving me about 70mph at 4K rpm, at 5.8k I would be going about 104mph.
I like my bike in 5th on the corners over about 40mph, I see no point in having risky amounts of power or torque available to me in these situations given the possibilites of having a 'bump - throttle response feedback cycle' bucking me onto the road.
My days of playing racer ended in the 70's with the repeated loss of much skin and eventually my, then beloved though amazingly stinky, RD350.
I love my bike and riding, but I want to live, I know how much it is possible to hurt and desire to avoid pain, I want to keep my mobility, I can have fun without grinding off my footpegs by taking pleasure in the weighless perfection of a perfectly controlled corner that left plently of residual capacity for dealing with the unexpected. I have no need to act out pretending that I'm a god, I'm not that blessed with superhuman abilites or imortality.
Motorcycling is dangerous enough without begging for your universal doner card to be punched.
Sorry for the sermon, there seems to be little of this preaching going on in here, in the face of so much bravado.
