I'm also thinking of getting a '06 SMR 510. I live in Australia and questioned the Husky importer on the suitability of this bike for the road.
Basically I was told, it's good for a couple of hundred kilometre day ride on variable speed roads, ie not a freeway. Any longer and the rider comfort takes out the enjoyment.
Whilst the owner's hand book states this bike is NOT suitable for road use, why have they even put lights on it and made it road registerable? Husqvarna's reason for road suitability is that it has no fan and the engine will not take extended periods of constant high RPM.
Also a key ignition can be fitted fairly easily. What is a poor design decision is to not put a steering lock on these bikes. Any bike with lights should get one. Piss poor effort Cagiva!
Now as far as maintenance, the importer told me. Do a first service at 200 kilometres. Dump the oil and filter and check the valve clearances. From then the "factory" maintenance shedule is every 2000 kilometres. Which isn't that bad for a performance bike I thought.
Does anyone else have any further information?
