My mate Liam was round for a visit the other day on his Suzuki DRZ 400 and let me take it out for a wee spin. Compared to the GS it feels like riding a pushbike, its light as fuck. Liam says that the bike had been geared for off road use by the previous owner, so you are always looking for another gear but a bigger front sprocket should sort it out. Its also a bit spaceshippy and futuristic with a digital display, a new thing if you're used to an old GS. I only rode the DRZ on the road but I bet it would be fucking great fun up the hills. I filmed my wee spin on the Gopro, the camera angle is a bit low though. Here it is.
On a completely different level is John Renwick's nitrous powered Vincent. Check out this video. It'll give anyone shed envy but wait till you hear the sound the fucking thing makes. Its awesome!
