I used to have a 2007 Yamaha TDM 900 which I thought was a very good motorcycle - apart from its looks. It had a very ugly 'shark' like profile but was a very able machine with comfortable riding position, 18" front wheel, excellent 'blue spot' ABS brakes and a sweet motor (84bhp) that was very smooth and super economical. It had a similar 270 degree crank but with 5 valves I think and capable of hugh mileages. It had adjustable front and rear suspension and gave a very nice compliant ride. I always thought it was a very sound design for a practical dual-sport bike. The AT is now the closest yet to take that concept and develop it to a logical conclusion (more so than the BMW f800). The TDM weighed 226 kgs (with 2 silencers and a 20 litre tank) and would have benefited from being lighter and I'm a bit disappointed that after 13 odd years of 'engineering evolution' that Honda hasn't managed to trim some weight from what is essentially the same engine and running gear configuration . I can only assume that the AT is 10% over-engineered to be on the safe side - when 1% of owners try to ride it like some of those riders we see in their promotional videos!
