They've all but gone, road legal anyway. KTM still do the 690, the 450SMR is a race only bike. Yamaha do the XT660x. If you're lucky you may find a Husaberg FS570 second hand which was one of the last true road legal supermoto's or convert an enduro bike with 17's and a huge front brake. I miss SM's but there seems there were too few of us fans to support it.
End of the Road for us then. The motard is ideal for urban traffic so `tis a great pity. CCM has purloined a load of BMW 449 engines and is putting out a new `adventure´ bike. Their site (http://www.ccm-motorcycles.com/) shows a very interesting frame technology and promises to use it with for a motard, so maybe it´ll be my future choice.
Your best bet is to pick your favorite dual-sport and then buy a set of motard wheels. The added benefit is you have the option of throwing the stock dirt wheels on if the need arises.
I think ATK still makes a 450 SM. I'm not sure if it comes as street legal but I think it's based on the 450 enduro and that can come as street legal. Also you could get the ATK 700 or 620 2 stroke along with there SM kit. The way ATK has always had their titles and MSO's any of their bikes can be made street legal with a little work.
"any of their bikes can be made street legal with a little work" Nothing´s easy in the land of the European Union
What a pity, cos Supermoto is an absolute blast and i dont really fancy a KTM, which is why i bought my SM610. I hate the fact that KTM has the market essentially cornered, we need more choice and innovation. I think other bikers that see someone riding a motard know that theyre having LOADS of fun, and they get a little knot in their stomach with the desire to own one aswell : - )
.. it´d have to be `homolomologated´ by the EU commisars. Am still waiting for CCM to get their 449 units into a super moto and on gthe market (I like their bonded frame AND the motor)
