top gear featured a car last year that had oil change intervile of 100,000 so maybe 5000 in a detuned 450 is not as bad as they say. The 15000 mile rebuild if thats a reality would be a pain

My wife's Mini has an oil change interval of 20,000 miles. What in God's name are we considering with this go anywhere bike - I buy one and change the engine at the same time as I'm doing an oil change on the car. All I'd be asking the thing to do is propel itself down the road at fairly mediocre speeds. I don't want to ride it to the moon, just to Tesco's. If it can't do that without the core part converting itself to scrap before the car engine is run in then there's something fundamentally wrong with it.
Back at the dawn of time when I started traveling / touring etc we used small air cooled two strokes and we'd get about 25,000+ miles out of them before they needed rebuilding. Forty years later we're considering a service life of half that on an engine twice the size!
Is there really a long life piston available? If there is presumably the long skirt bit means it weighs more. How's that going to affect the engine balance - am I going to get double vision riding it? Do I get an extra 10K miles at the cost of my fillings falling out? My current CCM really did give me double vision from wheel imbalance when I bought it. Good luck with trying to get an engine balance problem sorted out.
