The SLR is a lot better than I thought it would be. Comments about lack of equipment are just daft, it has a speedo and a fuel tap, what more do you need? Think of it as a trail bike and you're about there, it's basic and solid. I think a lot of the complaints about the SLR is because people put it in the wrong category. It's not a sports bike, a tourer, or a commuter, it's a trail / enduro bike so it should be compared to F650 / XT660 / XF650 etc, not bandits and SVs...
It's surprisingly good off road, only limited by the 19" front wheel and certainly better than the BMW F650 I used to own. It has a (small) bash plate and the frame goes right under the engine so you don't have to worry about grounding the crankcases.
The brakes are very good (twin piston Brembo up front) and the very large diameter forks give good handling.
Maintainance is a doddle, screw and lock nut tappets and a couple of litres of oil and you're done.
It will sit at 75 to 80MPH all day, but it's hard work on the upper body. For a trip to France I'll fit a windscreen.
The engine is a gem, great thunking gobs of torque from very low revs makes overtaking easy at any speed and cruising along at a relaxed pace is enjoyable with the reassuring throb from the big lump to keep you company.
I get about 55MPG, which gives about 110 miles to reserve, not ideal but the seat is designed for off road so you're ready for a break.
They hold their value really well, because people who know about these things know how good they are..
