I have an 06 model and would definetly recommend them and agree with the above comments:
+ve's
1.) Rear suspension is excellent (no linkages and the rear wheel stays on the ground matter how big the bump or step)
2.) Little / no maintenance required
3.) Smooth power for clubman rider but can be used for expert riders (ignition can be advanced and flywheels can be replaced with lighter versions). P.S. I'm a crap expert rider but there are good expert riders in our club who rider scorpa's
4.) I thought they were the same weight as all other bikes (sherco, gas gas, etc) with a weight of 69.5Kg.
5.) If you live in the UK the parts/service from the importer (Nigel Birkett) is excellent.

1.) Carburretor is not easy to remove and clean. However I have only had to remove once as i got water in it and that was again my fault as the air filterwasn't completely dry when I put back in.
Hope this helps
