[quote=“TainanCowboy”]Correct me if I am wrong, but the main 2-stroke/4-stroke debate centers on available torque at what RPM range.
It is characteristic of 4-strokes to have their useful torque available at lower RPMs.
For 2-strokes, their useful torques range occurs at a much higher RPM range.
(‘useful torque’ is not eacetly the right phrasing - but its what came to mind)
I personally prefer 4-strokes for their available low-end torque. Its what I forst became familiar with. Its what I personally find most comfortable.
I also am of the belief, after 30+ years of motorcycle riding, that 4-strokes demand less in terms of owner maintenance. Again - my opinion.
For 2-strokes, the power is there, if you stay in the RPM range to get it. And for many, such as myself, that range just makes the bike too damn squirelly.
YMMV…its all good.[/quote]Interesting points.
Stock 2-stroke scooter engines are actually lightly stressed. I’ve been none too gentle on my little Dio but it’s still going strong. And the narrow range of usable power is not a problem because of the continuously variable transmission.
Modern 4-cylinder 4-stroke motorbike engines rev fast! The CB400 I rented in Thailand didn’t do a great deal below 8000 rpm.
Still, I think you may well be right that 4-strokes are more reliable on the whole. My dad certainly thinks so.
My dream bike would be a 400-650cc v-twin.
