Riding hard?

My commute to school requires me to ride on the highway. In order to keep up with the 80-90 mph traffic in the i15 I really have to push the bike hard (over 7k rpms in 6th gear for 20+ mins at a time). I've heard conflicting stories from different people, some saying that this is bad for the motor and i'll kill it in 10k miles, and other people saying "well it wouldn't redline at 10.5k if it wasn't meant to be ridden at high rpms."

Just wondering if anyone could give me any actual insight into how riding at high rpms actually damages the engine if at all.

edit: meant 6th gear not 5th lol

It wouldnt redline at 10.5krpm if it wasnt meant to be ridden at high rpms

i do 30 miles each way commuting. mostly at 80mph. After 5000 miles ive had no problems. In between the 80mph stretches are round-abouts, which more often than not i open up hard when pulling away from. Still, no problems.

Edit: 80mph gives me about 7.5krpm in 6th gear, are you sure you mean 5th?

Misleading topic. I had no idea this was about RPMs.

I run my bike at 7500-8000 RPM all the time. I cannot help you much about whether it's good for the motor or not (although I suspect that there is little/no harm being done) -- it's good for my heart rate and that's pretty much all that I'm concerned with.

Hope the days that lie ahead
Bring us back to where they've led
Listen not to what's been said to you

You'll be fine. Just don't neglect you maintenance. I have to travel 70 mph highways for 30 minutes to get to my favorite curves, and then back, and it's handling it fine. I think. I'm about to do my first full service (plug, oil, both filters.) I'll report any signs of excessive wear.

I ride about 60 miles to work one way and I run about 75mph at around 78 to 8000 rpm for about 40 of those miles, no issues yet. I run Mobil 1 10w40 I have right at 3500 miles on it I change the filter every oil change its to cheap not to. My bike seems to be getting stronger with the miles......probably my imagination..,..

Change to a 15T sprocket.
At 70MPH am barely touching 7K RPM

I didn't like running the engine too hard in my mostly freeway commute.
I can ride at high speeds right in the engine sweet spot.

Running this motor at higher RPM's... 8000 to 10000... won't hurt it one bit. What will shorten its life, and give you an engine that performs poorly, is running it under load at RPM's below where the engine is really making its power.

Worst thing you can do, IMO, is to baby this bike.

Ride it like you f**king stole it!

Have you bought a spark plug for this bike yet? It's not your $2.95 run of the mill NGK... It's an $18.00 to $25.00 plug, depending on where you get it.

Not to worry... the replacement interval for the spark plug in the CBR250R is every 32,000 miles (51,200 km), with an inspection interval every 16,000 miles (25,600 km).

If you happen to own an Enzo Ferrari, you'd have to buy 12 of those $25.00 spark plugs. Bummer.
