I'm buying a new bike and need a bit of help. It's mainly a commuter bike ... so it needs to be good in the city, and skinny enough to squeeze through cars when they're backed-up at rush hour. My current Spada VT250 is great, but on longer rides and with a pillion I want something more comfortable, and with a seat on the back that doesn't look like an after-thought. I look at a Bonneville and think it's gorgeous, but is it practical as a commuter? I'd even go a scooter but haven't found one that I like with bigger engine. Is an SV650 or a Monster comfortable on the back? And one last thing, something that's not too heavy on the petrol will appeal to my greener sensibilities. Cheers! Andy.
