I think it may be a good idea to post my question on here rather than on a dedicated motorcycle forum as the idea may be a bit offensive. No offense is intended; it's just my ignorance.

We're thinking of getting a bigger motorcycle for longer rides. I currently use a small, made-in-Taiwan motorcycle, mainly for city driving, but also for short day trips into the mountains. The problem is it's not really the most comfortable thing for trips over an hour, both for the rider and passenger.

We're looking for a comfortable bike for longer trips, but it still has to work for city driving (and please be aware that riding a motorcycle in Taiwan is not like North America or Europe. It gets pretty intense here sometimes), so something bulky, like a Goldwing, is not an option. We don't want anything designed for speed or racing, just two people going for a comfortable ride. We don't need anything big; I'd like something under 1000cc, but I imagine we'd make out fine under 900cc or even 800cc (we're pretty light--combined weight of about 125kg). Nor do we want a crotch rocket.

The potentially offensive part is I really don't know how long a Japanese motorcycle can last. I hear about Harleys from the 80s still being used, and I'm wondering if a modern Japanese motorcycle can last 25 years--of course provided it's taken care of well and not badly damaged in an accident.

And, for that matter, can a modern Harley last 25 years as well?
