I think the issue here is what the bike would be used for, and what kind of budget there is. Think about this before thinking about brands. If budget is tight, bikes like a Thorn Sherpa or a Surley Long Haul Trucker are excellent, if budget is unlimited, Idworx is a superb off the peg bike. However, if you are spending that kind of money, a custom tourer would get my vote (that is how I voted with my money). But first, where are you going, what roads, how much luggage, what kind of rider are you? Are you doing fast credit card touring, round the world expedition style touring, or light weight camping holidays in France etc?
