CBXMAN is proud to announce that we have developed a Performance Enhancement Kit for the 250 Hyosung powered sportbikes from United Motors or Hyosung. This kit will work on all 2005 thru current 250 sportbike models.

This kit was developed in our shop and includes all the necessary air box, carburetor and exhaust changes to really make your 250 sound great and fly!

The details of the kit are secret but include important air box and carburetor changes. We can assure you that your bike will perform better thru the whole rev range. We can tell you that the kit with an IXIL Exhaust canister is designed with a removable baffle in case your area has noise restrictions. Remove the baffle and enjoy the full power of the kit.

We even include Mobil 1 Motorcycle oil with this kit and a new oil filter because Mobil 1 makes more horsepower. Don’t believe it? Read About Dennis' Personal Experience

IXIL Exhaust Systems:

These exhaust systems are available for seperate purchase.

The only silencers we know of that require no headpipe modification for installation. United Motors is the exclusive source for these silencers and they are available in a variety of styles. Truly a simple bolt-on installation. The IXIL silencer is equipped with a DB reducer that, when left installed, gives an agressive, mellow tone, but not too loud. Go to the track, remove the DB reducer, and you have an unrestricted exhaust. Silencer comes complete with mounting ring, gasket, and bolts.United Motors has made available four different styles as unique as your personal lifestyle. The top of the class is an oval, carbon fiber wrap with a conical end cap. Next up we have an oval, aluminum wrap, again with a conical end cap. Then we have a round, stainless steel wrap with a conventional end cap and for the adventurous, we have an all new "xtreme black" wrap with a conical end cap.

In spite of their different designs, the sound is identical from all 5 pipes.

Dennis' (President of CBXMAN) Personal Experience With Mobil 1

Here's a story I heard back in the early 80’s from a Ford engineer named Tom H.(last name withheld) who was heavily involved in the development of turbo motors. Back then Tom H. told us that at Ford they had taken a four cylinder motor and run it on the dyno and then drained the oil and replaced it with Mobil 1. The engine showed an immediate 5 hp performance improvement and ran cooler to boot. That was enough to convince me that Mobil 1 was the way to go and ever since then it’s the only oil we use in our bikes. Tom also told us that they drained the Mobil 1 after 4m miles and strained out all the solid materials in it and put it back in the same motor and ran it again for many more miles with no ill effects!

We've used Mobil 1 in our CBX's and all of our high performance bikes since 1990. We have never lost an engine!
