Mine is the X, the Supermoto, I am in to my third year of ownership, 2 of us bought these at the same time, we ride them for fun only, out on twisty tarmac roads, moor roads etc, we both think that these bikes are the business and neither of us can believe that we prefer these to sports fours, it takes a while to get used to a single (no revs change quickly) and a while to get used to a Supermoto bike and what it can do with the right warmed up tyres. Some sports bikes do pass us, in the three years we have had them probably around 8 only!! First we thought that we were steady riders but a maybe a little quicker than average Joe, now since we are riding in areas where there are loads of sports bikes (hundreds) we realise that these Supermoto bikes are perfect for tight twisting roads, we use three quarters of the bikes power and all of the gears, Sports bikes are blasting down the very short straights but in second gear and slipping clutches round the tighter bridges and bends, we are riding at a steady rate but the wide bars, long travel suspension and ludicrous roadholding and lean angles makes riding effortless for us, we are getting, one up, around 69 mpg!! A day out for about £12-15, around 45- 50mpg two up on the same tight twisting roads.
You have to have a go on one of these on roads that suit them not up and down a motorway or straight A road they are a superb machine, plus if you want it is easy to lose 10-20KG off them and add a bit more hp but we have enough fun as they are.
Only complaint? The seat could be slightly more comfortable, the seat gets you off the bike not boredom. Got to be tried to be believed.
