Even though the Ultra 250X is still a newborn and just arriving at the PWC dealers, many aftermarket parts suppliers are stocking their
shelves already, aimed at beefing up big time the supercharged 250X and 250LX... Is it time to modify the new Kawasaki watercraft?

Let see who is offering the latest 250X modifications:

GroupK Performance of Ft. Mohave, AZ.

GroupK is offering the Stage-4 ride plate modification for $140. It's claimed that combining it with the 250LX stock, pump nozzle wedge, will give the Ultra 250X a top speed increase of 3mph, which is very big gain for the money invested.

GroupK's high performance research and modifications, run by the respectful Harry Klemm, its owner, are well known, and very respected, in the Personal watercraft industry for his detailed online disclosure of the time consuming research and development they conduct on personal watercrafts. I should also point out that GroupK was the high performance shop in charge of the work done to the 250X that won the 2007 endurace race, the "Mark Hahn Memorial", at Havasu. Congrats, GroupK!

There are many others personal watercrafts shops working on the modifications for the ultra 250 but I couldn't find anymore information for pwc aftermarket parts, or modifying work, available as 4/10/07. This new Kawasaki watercraft is hot and many horsepower builders shops are working hard to make it the fastest personal watercraft for the next world final championship!
