Hmmm, more or less what my gear calculateor said. But surprisingly not what the GPS says. It is actually quite a bit longer on the GPS. 13900 in 6th the bike is actually doing 307 kph. Checked on 2 bikes with 2 different GPS's. I did not get it but that is the evidence. By the way, the red line may be at 14000, but the limiter is at 14200.
I used a piece of chalk to draw a mark on the rear tire. For the Metzeler Racetec K3. 32 psi., with rider weight added, rolled forward a few feet to transfer the marks to the pavement. I measured the distance between the marks with a tape to get the rolling circumference.
I put a piece of reflective tape on the rear tire and raised it off the ground with a bike lift. I put the bike in 6th gear and ran it up to an indicated 90 mph. An assistant used an optical tachometer to measure the rpm of the rear wheel from the reflective tape.
From these measurements I was able to make the following conclusions:
1.) The S1000RR tachometer on the instrument panel is about spot-on accurate.
2.) The speedometer is also very accurate, reading only 1.6% high at 90 mph.
I was able to derive the maximum speed in gears at 14,000 rpm as follows:
That is just about what I have. This will never be 100% accurate due to growth and slip on different tyres. My super corsas are slightly smaller that the Metzlers giving slightly less speeds.
yeah i got that from the manual, i editied the post so i assume thats what youre replying to haha. thanks though! is it a 520/525/530 chain? im trying to order a vortex sprocket.
i see mention of upgrading to a 520 chain, so i assume its none of those?
Since you guys seem to love calculating speeds, can yall give me the top speed for each of these gearing combos: -1, -1/+1, and -1/+2? Love you guys...
I agree with the 3rd gear 143...as I go through the speed traps in the 1/4 mile, leaving it in 3rd gear, I hit the rev limiter at the speed traps or just after and the terminal speed is 142.....nice...
Final gearing has changed since 2010-11, someone will have to recalculate everything. Maybe the guy that brought this thread back from the dead...
