Considering a KX500 for street bike conversion

[PaulBWatertownCT]

Hi all,
I have had many, many bikes over the past 25 years but have always had the itch for a 2 stroke streetbike. I am considering buying a KX500 and transplanting the engine into a 2008/2009 Ninja 250R. I have been doing some extensive research and believe the motor will easily fit into the 250R frame with some custom motor mounts for the front of the engine. Some larger rubber and steel braided lines would be my only other mods.

I would appreciate any feedback on thoughts regarding driveability, vibration, or other thoughts and ideas. My purpose is to have some fun and ride something fast, different, and a complete sleeper. I figure I can buy a new or almost new 2008 Ninja 250r for about $3500 and I have seen some excellent condition (like new) 2000 or newer KX500s for around $2500. For $6000 plus some garage time and a custom pipe, it sounds like a solid plan.

My current bikes include: 2005 KTM 300 MXC, 2002 KTM 200 MXC, 2002 Aprilia 1000.

Past bikes are too numerous to list but started with a 1975 Yamaha GT80 and run through 2007 Ducati S2R1000. Favorites include 1986 GSXR1100, 1996 TL1000s, 1993 GTS1000, 1997 CBR1100xx.

Let me know your thoughts (and I do know it would be cheaper and less hastle to buy a new supersport bike but that not the point).

Thanks,
Paul B.

I think that would be a pretty sick bike plus your getting a 250streetbike off the road too

hey Paul I've been thinking the same thing, so ya its a good idea. I have looked at the 07 250 and it looks like it will work. I think the ninja is to heavy, so im just going to motard my extra 500. I dont know if you could call anything with a 2-stroke 500 motor a sleeper. When you get finished let me know if it was worth it.
