Joesax: ah… Thailand… what a place… much envy going out to you for your upcoming trip, sounds great!.. as long as you make a big deal about declaring the items of significant value both on the way out of taiwan, and into Thailand, and as long as you bring them back with you, I doubt there will be any significant hassles at customs…
Maoman: 2400cc hehe… i sat on that bike at the Triumph stand at the Milan International Bike expo last month… it really does re-define “excessive”… you could elbow gravel trucks off the roads with that thing

RE: www.siamsuperbike.com … well, reasonable prices for used bikes i suppose, but they seem to have very few late model bikes in stock other than the Hayabusas which are just ‘not’ suited to Taiwan… as for whether it’s a good idea to import such bikes from Thailand… well, yes and no… dealing / importing used bikes is a very risky and/or tricky business for 5 major reasons:
1.) unless you, or someone you trust implicitly actually goes in person to check out the bike/s from top to bottom, you just never know if you’re going to get a lemon… with parts and servicing for big bikes being very expensive in Taiwan, it’s doesn’t make financial sense to get a “fixer upper”…
2.) the price you’ll pay will be approx market value for the country of origin, but since it’s second hand (or older), will unavoidably include local taxes… since it’s a used product you will not be able to claim these taxes back on export, also once you get it to taiwan you’ll be taxed on total value, in effect paying tax on the tax… this is not good…
3.) to import a used bike, you need to provide proof of previous registration in the country of origin, and cancellation of said registration… these documents will in all likelihood need to be “authentificated” (sic) by the taiwan trade and cultural office in the country of origin… the beurocratic imps who staff these kinds of offices both in other countries and in taiwan strive constantly to take ignorance, incompetence and inefficiency to new heights… this is not good either…
4.) once you get the bike here, there will be confusion from the customs people since they don’t usually deal with these types of import processes and documents, this will be construed by them as a potential loss of face, when taiwanese beurocratic imps (see above) perceive a potential loss of face from having no idea what to do, they usually react by declaring whatever you want done impossible, illegal or non-existent and throwing red tape at it until it goes away… this is really not good…
5.) for similar reasons to those outlines in point 4, the license application process could become very tricky indeed… not to mention the fact that a used bike may not even pass the EPA test…
as usual i’ve only really emphasized the potential problems, get it right and if you’re lucky you could get a really good deal and a great bike, but just to make you aware of the pitfalls…
on the topic, this clarity.net/~adam/buying-bike.html#4 is an excellent guide for what to check when buying a used bike… follow these guidelines and you won’t go far wrong…
