Maximum speed per gear before hitting rev limiter?

This thread made me pay attention going to work yesterday. 3000rpm is right at 80mph on my standard.
It needs a 6th gear BAD!

HellFire..would we then lose this bike's ability to roll on in top gear the way it does
a part of the bike's performance i really like

6th gear

I still reach for 6th sometimes but not as often since installing the GI Pro. (What a great device.)
 
NO point in gearing the bike any higher the speed limits arent high enough and cruising at 80+ mph is only going to get you a ticket or worse
 
I absolutely agree about the need for a 6th gear. Where I live if you're cruising at 75-80 you'd better be in the far right lane. The speed limit is 75 and 10 over is probably the average.

the general idea and consensus among most R3 riders has nothing to do with speed but to lower the RPM
 
WE CANT really cruise around here at much over 80 but there are plenty of CRAZY FAST AND FURIOUS car nuts flying along at over 100+ passing and weaving thru traffic
 


That is exactly what I was looking for and seems to be pretty accurate (if the speedo is accurate that is......). Therefore, on a stock R3T with max HP at 5400 rpm and 5800 rpm redline, full blast acceleration shift points should be as follows:
  • 1st to 2nd at 45-50 mph
  • 2nd to 3rd at 70-75 mph
  • 3rd to 4th at 95-100 mph
  • 4th to 5th at 120-125 mph
A couple factors to consider however would be:
  • The overall speed limiter kicking in at 130 mph means you might as well stay in 4th since the 5800 rpm redline gets you to 131 mph in 4th anyway.
  • A somewhat early shift into 4th may be warranted due to the timing retard limiting power in the first three gears.
  • Or, just install GI pro with ATRE and go faster!!!:bch:
 
As the RPM's climb, and the torque gets replaced by horsepower, it's like a "let-down". I never thought I'd say something like this ..... but phooey on horsepower, I want more gear so I can stay in the torque curve longer. It's the "grunt" that turns me on these days, the rocket thrust-like pull it does before the RPM's even start to climb is where it's at for me. My hopped-up MINI has horse power, but is lacking that "Umph" feeling as the throttle is mashed. When you wind it up it goes like a bat out of hell, with the way it's geared and having a 6th gear to cruise in, you spend alot of time downshifting. Same with all the bikes I've had in the past, lot's of downshifting for the revs. An R3 with a 6th gear would be the greatest bike ever made! Hell, I bet it would cruise comfortably at 170mph while a Hyabusa would have to be buzzing like a hornet to maintain the same speed.


Triumph, please build me a 6 speed !!!!
(Do you think they heard me?)
 
A MODDED ROCKET makes even more trq as the revs rise 196ft lbs and 245 hp or double what a stocker makes so no need for 6 speed 8000rpm =212 mph

Another option would be to have a taller 5th gear cut.
I have actually talked with a local gear company about doing just that - 10-12% taller to drop cruise 300-360 rpm. Not enough to drop off the torque curve, but enough to be significant.

Better material, micro-polished, nitrided, and cryo-treated for efficiency and strength.

The problem is the cost and minimum order to keep set-up costs realistic. I am not sure if there is enough real demand.

Have a better star shifter and heavier spring produced at the same time - for MUCH improved shifting.

Something to think about.
