So.. along those lines...

What constitutes "high mileage" on a bike?


I had a student not too long ago ask me about my bike.
I said: It's a 2007 CBR1000RR. I haven't been riding it as much as my previous bikes, so it's only got about 25k miles on it now.
Student: *gasp* Oh no! You're probably getting ready to do a complete engine rebuild with that kind of mileage!!!

So I went through the explanation that, with proper maintenance, motorcycle engines can go tens of thousands of miles without issue.

He asked a question very similar to OPs.

I said that I'd just do the math, for example, let's look at my 2007 with 25k miles on it:
Assume riding season here is March to Oct (for those fair weather riders). That's about 8 months.
My bike is 7 years old.
25k divided by 7 comes to 3600ish miles a year.
Divide that by the 8 months, that comes to 450 per month. Not exactly astonishing... 110 miles a weekend if ridden every weekend?

My bike has done a LOT of sitting the past couple of years.

With that much sitting, I'd be worried about old tires, flat spotted tires, old gas, old oil (MOM says oil change once a year or every 8k miles, whichever occurs first), old other fluids, rusted/kinked chain....
See what I'm getting at?



*** My bike sat because of where I worked. Nice roads, but no traffic and no real benefit to taking the bike. Plus the Jetta TDI blew the CBR out of the water for fuel efficiency. And it was nice sipping coffee, listening to audiobooks, having heated seats on those cold mornings.... I'm riding almost every day now to Reston because 66 is the major suck, so my mileage is going to climb fairly quickly..... well, unless I continue to use Donovan's V-Strom 650... this *his* mileage will increase.

An engine with an oil leak can be toast in as little as a few hundred miles. An engine that suffers infrequent oil changes can be toast in a couple thousand. A properly maintained Japanese inline four can last a hundred K miles. You have to read the seller and the bike's appearance. You can get a better idea with actual quantitative metrics like compression, leak-down, and Dyno performance. Or you can take your chances since we're not talking but a few thousand dollars anyway.

I have bought several used bikes. I never buy from a clown, and if a bike looks like a POS, it probably is. There are typically no diamonds in the rough.
