Running RX3 past 8000 rpm?
Hey folks,
So I have a 40 mile each way highway commute I'm doing on my 2015 RX3. There is a great secondary road I take when I have time, but more often than not I take the highway for time's sake. I'm running the bike at 8000 rpms in 6th gear, but find I dip into the tach's red zone. Any feedback if the Redline on the RX3 is really to be avoided? I have yet to hit the rev limiter. Dave |

You don't mention if you are running stock gearing. Mine is geared stock and I weigh under 155 lbs fully suited, so not much of a load for the engine.
On my freeway commute I would occasionally hit the rev limiter when passing cars. However that's a theoretical 90 mph and don't recommend it. The stock gearing should give a 6th gear redline (9000 rpm) speed of 84 mph, above 75 mph at 8000 rpm. Is that how fast you are riding?

Good point. Up one tooth from stock on front sprocket to 14 I think. Otherwise stock. I'll double check my speed w/ my iphone/gps next time I ride. I'm 200lbs ATGATT with another 15lbs in luggage.

I recall seeing a post to the effect that the ECU has a hard limit of 11K rpm. That tells me that 9K is a conservative limit and not a destructive range. With stock gearing and a full load of camping stuff I found WFO to be about 74 mph (GPS). I'm not sure what that was in terms of RPM but it was the limit of what I wanted to do on the bike.

Stock gearing is 14/44. CSC doesn't offer a countershaft sprocket above that, only a 13 tooth which would allow the engine to more easily rev in 6th gear.

I have done long stretches at 8800 RPM without issue. I've also hit the rev limiter several times at 10500 RPM. I've got 13300 miles on mine.
