RPM Question
Hello all,
Just bought a new 2012 Ninja 250, and am a little concerned over the RPMs I'm seeing. I've read an awful lot of posts on various sites about "normal" RPMs, and it seems that my 8,500 while going 60 MPH is very high. Are they normally higher for a brand new bike or is this likely a mechanical issue? |

Welcome to the site, Phil!
Perfectly normal. These engines have been designed and manufactured to perform at high rpm's. Mine has been turning at sustained 10K rpm for several thousand miles (highway commute) and is as happy as new. Now, keep an eye on the oil level and oil light: a few seconds without proper lubrication and .........bye-bye engine.

I'm glad to hear that, but...if it is normal, then why do so many people with similar heights/weights to mine have RPMs that are so much lower (e.g., 6000 at 60 MPH)?

RPMs are going to have nothing to do with the rider height/weight. It's a fixed number based on the gearing on the bike; nothing more, nothing less.

Sounds like you have a faulty CDI that causes the tachometer to read an extra 1000 RPM. Most new gens do it. Mine does. Search and ye shall see.

When I bought my new ninja last summer, I was always trying to shift to 7th gear because of the high RPM's.( I don't count gears when shifting) This spring I changed to a 15 tooth front sprocket. It makes a world of difference. Everyone says it makes 1st gear more usable but I think it feels more like it gives you another gear at the other end. Merging on to the highway, hitting 65 in 5th gear feels like the old sprocket. Best Mod you can do to the bike.
