Sold a 30 year year old, great running Honda 500 V-twin to a young rider a couple of years ago.

Explained that she had six speeds and advised that he NOT run her up to red line of 9K rpm's.....cause she's 30 years old.

He promised not to.

Then---3 days later, he ran her up and she came apart.

Nuff said.

Well, I tried guys.

That's gotta hurt, to have her die like that. But I see and hear it all the time these young people revving the sportbikes as proficiently as the HD guys blipping the throttle. It's an art. But riddle me this: didn't you race the carp out of stuff when you were young? I know I did. Damaged more than one motor and totaled more than one vehicle in my day. Yeah, it's a shame but that's youth. Maybe you should have passed on the sale. Being one of the "if you have to say it" situations you probably knew it deep down. Plus by saying not to you basically double dog dared him to.

I was fortunate that when I was a kid one of our neighbors was a very wise maintenance manager for a steel plant and taught by example and with lessons how to work with mechanical items. His basic approach was, respect machinery and it will treat you well. He would get more miles out of their car engines than other people and then rebuild them himself. So I never crashed or ruined a piece of machinery. Another reason was that I couldn't afford to. I had a Yamaha 650 for 30 years which I didn't rev to redline, gave it to auto salvage person when I couldn't get parts for It any more. The engine was still good so he used it to make a go cart for his daughter.


That young rider didn't listen to someone who gave wise advice and so he paid the price!

How many miles on it? These Japanese bikes are tough. But the old ones don't have rev limiters and can be over revved.

I am 60 years old and still bang my 30+ year old 454 to that 10 grand redline at times. All in the lower gears though as I have no need to go 100 mph any more. I think 80 is about as fast as I have had it.
Every bike I ever had I redlined and never dropped a valve or grenaded an engine.

It has 27k on her, I think. Been awhile since I checked but I keep her maintained pretty well.

+1 and I have to disagree with the sweepeing comment of "dont red line her",
I ride on the street only vintage stuff, my main ride is a 37 year old KZ750E that often gets taken to redline on it's stock engine, I ?ften do long stretches at 90 mph (doable here on italian autostradas).
in the weekends i road race in the national vintage cahmpionship, always taking motors way beyond stock redline
and this very week i took to the track a stock 1984 gpz550, did three 20 mins track session with her, constantly taking her to 11,000.

These motors were designed with these rpms in mind, no problem talking them there. of course that if valve springs are tired, piston has slop and eats oil, etc. then you are looking for trouble. but on a decent condition motor? cant see the issue, quite the opposite... in italy we believe that taking motors to the redline does them only good, seriously, it's called "italian tune-up"

sorry for the young dude but maybe the advice to him when buying the bike should have been, change the oil and filter, check the tappets and cam chain tensioners, warm her up well before pushing, etc...
