I've had my '97 Dommie for for seven years now and have used it as my all-year round transport to work. Rain, snow, sleet and ice the Dommie has seen it all and so long as I keep on top of the cleaning the finish still looks quite good; winter road salt will eat it alive. A regular change of the oil and filter ever 3,500 kms is an absolute must along with regular checking of the oil level. Mine doesn't seem to use much but I've heard stories of some engines being a bit thirsty and owners letting the level run low resulting in top-end rebuilds.
Mines now done 51,000 kms and the only thing I can fault it on has been the starter motor letting me down but with new brushes it's working fine again. It used to be the butt of a few jokes from the guys at work who occasionaly commute in on their sportsbikes (only when the sun's shining of course), but with a couple of weekend rideouts with them along some twisty back roads they are a lot more respectful. It's gets a bit breathless on dual carriageways so keep clear of these whenever you can, but it is so gratifying to ride quickly along the back roads that afterwards it's a struggle to get my crash helmet off because of the huge grin I'm wearing. With 10bhp more and a better front brake this bike would be 10/10
I get just under 50mpg on the commute to work and 55mpg on less congested rides. Apart from a Hagon rear shock, the original saw one winter too many, the bike is standard. I keep thinking about swapping it for something else but I just can't bare to part with it. Perhaps I'll have to make some space in the garage for another bike.
