I don't have any numbers to say but the Burgmans wet clutch hooks up faster with less slippage off the line vs the dry clutch on the MyRoad. Off the line feels pretty good compared to the Burgman. At speed there's no doubt that the Burgman is faster in passing with the wonderful electronic CVT. In Power mode the Burgman is even more impressive. On the MyRoad I sometimes look for the Power button at times either for faster passing or for engine braking slowing down.
I'm not one with a throw away mentality and I am capable of doing my own repairs. I love my '03 Burgman 650 despite having a fairly expensive CVT failure at only 26,000 miles. Fortunately I waited long enough to repair it that upgraded parts became available (the Polish adapter and Suzuki's updated primary pulley assembly). I have since ridden the bike up to 43,000 miles and continue to ride her in between my other vehicles. My '09 has had no issues but I have stopped riding it as I would also like to upgrade the primary pulley assembly in it, she currently sits with just over 22,000 miles on her.
It's quite interesting the things that are the same between the two and yet what's different. The MyRoad and Burgman 650 share the same size tires and type/size spark plugs. That makes carrying some maintenance parts a bit easier for me with these bikes. Different between them is ergonomics, Suzuki knows all about this and it seems Kymco knows nothing about it. One major issue on the MyRoad is the seat shape and placement of the rider. This should be nothing new to Kymco as nearly every review I have ever read complained about the seating and mind you this bike has been around since 2008 yet they have done nothing about it. It's the single biggest change they could make to improve the bike. A couple of other things I've noticed are what I feel is excessive effort for the use of the brakes to stop the bike and the brake levers only have 4 adjustment positions where they do not feel close enough for me (the Burgman has 6 positions). Fortunately I found the Dimotiv brake levers which change the leverage point reducing the effort to pull in the brakes and have 6 position adjustability. The handle bars are a bit odd as they have less sweep (more like a 50cc scooter than a maxi scoot) than the Burgmans. At some future point I may do something about the sweep. The under seat storage is quite a bit smaller compared to the Burgman. The fuel tank is smaller and requires premium fuel.
