Who's CBR300R has done the most miles?

Not me. I've put less than 4k miles on mine in 2 years. My job is 3.5 miles away and the scenic route makes it around 8.

Has anyone got any idea of how many miles these engines will do?

That's a good bit of miles to rack up, I crossed over 7000 on my F the other weekend. With only 8 mm of crank difference and cams being changed on a under stressed motor, I imagine you would still easily hit that 32k from before and then some. That is unless some other driver decided you don't need you bike again.

Well I put 30,000km (18,600 miles) on my cbr before I sold it but there must be riders on here with possibly double that by now? This model bike was released four years ago after all.

I just had a quick look on CBR250R.net, and some guy had managed over 98,000 miles on his!

I thought I was doing well at 6000km (3700 miles). Apparently that's nothing. Although I live in Saskatchewan, Canada, where winter is 13 months long...
I'm amazed that engine can run for such extended lengths. Absolutely amazed.
I do oil analysis on all my vehicles (including the CBR), Its already some interesting results - I will post the results on this forum sometime this fall. It would be interesting to see the results of a truly high mileage CBR.

Mine has just under 16,500 on the CB300F. Trying to not ride it right now while I save some pennies for the 16k service with new sprocket & chain (upgrading to 15T)

Would be interesting to know what the compression number is on that motor. I'd think at that mileage it's more than likely a candidate for a fresh top end.

All things being equal, if average rpm is 6000 then that’s 3x the revolutions as a car engine averaging 2000. But if you factor in the short stroke it’s probably comparatively less. So 98k is like a car with maybe 250k. Not that unheard of. Probably not problem rolling another 50k before it needs a rebuild.

100k on bmw touring bikes and goldwings is pretty common.

I'm closing in on 22,000 km right now and have had zero issues so far. I replaced the tyres with some Pirelli Sport Demons at the 12k service purely because I wanted more grip in the wet... the OEM tyres still had life in them but I span up the rear wheel more than once while commuting and so wanted something stickier. I replaced the chain about 17,000 km because it had a few kinks and commuting without enough maintenance hadn't been kind to it. Needless to say I'm trying harder with the new chain!

I got almost 95k and still perfect, I'm just doing about 100km daily, from work to home 52km go and 54km coming back, i bought my baby when it was 17km. CBR 300r 2015

That's awesome, good to hear. What have you done to it other than change oiil and filters and tyres and chain and sprockets? Spark plugs? I'm guessing you've had the valve clearances checked? Has your bike had the crank recall done? Apologies for so many questions
