My Brand new KLR, RPM is different.

Hello all

My insurer has replaced my 2017 KLR with a brand new 2018 KLR after a car ran into me about a month ago.

I have included a picture of each. The photos are taken at the same local locale. Each photo is taken on the first weekend I owned each bike.

Anyway, I have a question for the experienced and knowledgeable members.

I'll preface the question with an explanation. My old bike, which had done about 24000 miles sat on about 3100 rpm at 37 mph. The new bike, which has done about 80 miles sits on about 3020 rpm to maintain the same speed.

I did have a feeling the old bike was doing slightly more rpm to maintain that speed, but I convinced myself that I was being paranoid.

So, my question is; why did my old bike do more rpm to maintain the same speed.

I welcome any thoughts or advice

Thanks guys

Imprecise measurements from inexact devices.

Yep, the KLR speedometer and tachometer are only suggestions of motorcycle or engine speed!

Thanks for accepting thoughts or advice. I have more thoughts than advice these days.

So my thought is - global warming. Ya, the air temperature is warmer, which makes your bike run better, at lower rpm and using less fuel to do it.

The KLR speedo and tach are as accurate as the fuel gauge ...

If the rear tyre is less worn then it would need lower revs to do the same speed.?

what they said.....if the rpm difference is real then the only other possibilities are gearing (sprocket) differences or tire circumference differences.

With a Hardline brand digital tachometer, I have found that the KLR tachometers are not very accurate either.

So with variance of both meters between two bikes, 80 rpm doesn't surprise me even a little bit.
