A bit about my specs: I've been scooter riding for 6 years, doing 25k miles in London commuting on two 125cc machines. My current one is a Pcx. I'm looking to move up, and this will be my first bigger bike. 90% of use will still be city commute within London - so being able to weave through traffic is important. But I'm definitely looking to add more fun in the mix, with weekend trips, fun rides, the occasional 4-5 day tour. I'd like to do some of those trips with the missus. (Ideally I'd love to do all wither but we have a little child so logistically that's hard, for now) I'm quite tall, 6'2", while my lady is petite and skinny, I'd say our combined weight is around 280 pounds / under 130 kg. I want something that can take both of us comfortably on those occasional trips - but I'm not at all interested in extensive motorway riding, more like A/B roads where possible. Budget - not really set but probably can squeeze out around £4-5k.
My current shortlist of bikes:
Honda Forza 300: based on Honda's marketing spiel, it's just the bike for me: same styling as pcx (which I love) but bigger, more powerful, practical, ABS, comfortable two-up, with good economy and Honda reliability. My concerns: how much will it cost, lack of proper screen, power on lower end (is it enough?), is it comfortable for my height?
Burgman 400: a proven all-rounder, choice of many muppets here, looks good, does everything. Concerns: is it too bulky for heavy London riding, expensive new and used ones don't tend to have ABS
Tmax 500: a bit of a wild card, but like the thought of the famous motorcycle handling, and I feel like it would be the most fun on those weekend trips down some A/B roads. But: expensive (could only afford 2009-2010 used model), and no ABS
I've considered others notably X10, Majesty, sym/kymco but they tend to fall below the above for various reasons.
So, what do you all think? Am I moving in the right direction? One problem is of course I haven't ridden either of these - the forza is not out yet, and the others I'd have to buy used, so it's hard to get a test ride. What else should I consider? How important is ABS?
