you can find on the net the RPM for peak HP and peak torque. between these two is where you want to be for max performance. peak HP would be near around redline, probably a little under, and peak torque ~10K IIRC.

I personally cruise around 7-8K rpm, and when the road gets twisty i might shift as high as 11, but normally around 9-10.

take note the red line is 13.5K, so 7K is like 3.5K on a car.
if you are riding this bike between 3K-5K, you can get another, cheaper bike. you are not even tickling it

 

so im assuming i can cruise at 6k and all will be well? shift at 7 or 8?

 

Your over thinking things, shift whenever you need/want to, just make sure the engine doesn't labour.
These are high performance engines designed for high revs, they are pretty much bullet proof so shifting at 7 or 8k isn't going to destroy it.

 

Just want to say thanks rpmraper, Ive been following this thread and Ive been wondering tha same question as well. But I love going through tunnels now

 

glad to be of service, i was the only one brave ( or stupid ) enough to ask lol

 

Well I wouldn't say stupid hope you get your speedo problem figured out

 

yeah im gonna try and put the volt meter on it later after work thanks guys

 

I was like that when I got my bike, just after passing my test. The CBR engines are strong, 100k is not unheard off. Find some quite roads and get the feel of her beyond 10k, man these bike turn into rocket ships beyond the 10k mark, it's where the fun is! Near where I live there is a quality bit of road with a long straight climb uphill. In 3rd coming up to the read line she's like an animal and the front starts to lift. The best feeling in the world! Leaving cars chugging up the hill like they are going backwards.........just thinking about it makes me want to jump on the bike and do it one more time.

 

Most F4/F4i riders will never (or unlikely) to truly explore the bike's designed track potential. When I'm on the track, I'm riding a dif way than I am on the street. There's a lot more engine-braking, which is w-a-y up in the rpm band. Conversely, when I exit the apex, I'm rolling on the throttle w-a-y up in rpms as well. Point is, let it roll baby!

 

Wow gotcbr I just got your picture; a bolt very nice. /hijack
