Where's that build from years ago, guy put a kx500 engine in a ktm frame I think it was

Two Strokes…?
So it was reliable! 😛
That's the moto equivalent of cross dressing. 🤔
I wonder how often brands test bikes that only a select few know about, or discuss. Think of the YZ150R, or the aluminum frame RM 250 that was by all accounts, unrideable.
You read this one, but
I mean, mxa just put out the rx250 is 40hp and the rx350 is 48...all im saying is it can't be any worse than that right? Thing probably outruns the 450 off the gate and they are needing to tone it down. Buddy has a stock 24 kx450 and let me tell ya, its not that far fetched
TBI 300 makes less power then a YZ250, but yeah, sure, bro.
Still going strong! Have it in the garage still. Finally got a crank a couple years ago after well over a couple hundred hours and A LOT of racing on it. Still love that bike just as much as I did when I first got it. Knew a lot of people that couldn’t keep them together, but I never had that problem and still haven’t had that problem. Heck, I didn’t put the radiator cap back on properly and lost almost all the coolant in a race at Glen Helen in the middle of Summer when it was well over 100. No damage done, filled it back up an raced if for another 150+ hours.
Any pictures of either of these?
This is actually a KTM I think
My 05 was awesome, I rode the crap out of it and it never let me down, I was however going overboard on maintenance as I was an apprentice scared to death about blowing a four stroke up..
Not true! If your talking KTM 300 XC/SX, those typically dyno between 50-53 hp. YZ-250's usually in the 47-49 range.
It is, but with a KX500 engine in it. Another shop built a KTM with a CR500 engine in it and they did a back to back race off kinda test with both of them.
Pit Row
KX500 in a steel frame with KYB, even comes with an FMF pipe.

Mine let me down at Ironman. It finished the race but it spun the cam gear half way into the first lap. No power ☹️
Sorry, no. The RM was tested by Rich Taylor (and probably others) in Cali. The YZ was seen in an Ohio warehouse, but I can't recall anything with testing other than it wasn't working out, and got shelved.
Finally what I wanted to hear now I can get some sleep!😅
No shit…
Here is a picture of an aluminum framed RM125 that was raced in the All Japan Nationals around 1994. The riders felt that the frame was too harsh and it never moved forward. I took this picture around 1996 as it sat collecting dust. The frame was absolutely beautifully done, though.
As the owner of both bikes you’re absolutely wrong and it’s not even close. The KTM 300 is closer to my yz450 than it is to my yz 250.
Amazing grab so cool to see.
I’d love a thread of the one off bikes and tech at the all Japan nationals. Seems lots of stuff is tried there and doesn’t move forward.
Last year it was power steering on the Yamahas.
Was anyone sued in the process?
Oh the irony...LOL
To all you guys supposedly waiting around for the Kawasaki: get real, you arent going to buy it anyway. you will talk yourselves out of it when it arrives. There will be some issue you do not like and you wont buy it.
why do I say this? simply because there are similar , advanced, fully developed two strokes in showrooms NOW. There always have been. A serious buyer would select from what is available and ride on, not wait years being strung along. for some it is just a pipe dream. or expansion chamber dream
This definitely has truth to it. The factory GNCC team all run KYB over Showa, the only other thing I heard tho, was the bike Stu Baylor rode on his trip to Japan, he said it was way too aggressive for a production bike, never really heard about anyone else riding the bike
