Swapped this 250 KTM 2015 for my 450. Rode it for approx 1h 15mins and then engine blew mid air. Sent me over the bars landing on my shoulder. Snapped the humerus up in the shoulder and ligaments torn off the bone too. Op done and now recovering so I decided to whip the engine out and see the damage. I wish I hadn’t now sick sick sick

There may be people that have more talent than you, but there's no excuse for anyone to work harder than you do.

Holy shit dude. That's some bad luck, glad to see you weren't hurt worse. Is anything even salvageable? Possibly the clutch case?

Well I wouldn’t say that. I’m expected to be off work 5-6 months! The bone snapped into about 4 pieces pinch From what I’ve taken apart so far, the clutch looks good and all the cogs. Power valve okay too. Haven’t split the cases yet but I hope the gears are reusable. Just looked up some prices on parts and it’s already setting me back around £1300 sick and that’s hoping the gearbox is fine.

Is that OEM connecting rod and crankshaft? I had similar incident with my 150sx with Hot Rods aftermarket crankshaft in it

How many total hrs on the bike? History? Wow...that is catastrophic!

9/23/2018 2:41 PM

Anyways- heal up!

9/23/2018 3:11 PM

holy detonation batman

If it can't be fixed with a hammer, it's an electrical problem.

HFS.

Part it out.

There is no need for parting the bike. You can find used engine cases, crankshaft and cylinder fairly easy for 250SX. I think engine cases from 2003 to 2016 will fit your bike and same with the crankshaft. Cylinder and cylinder head are same trough 2011-2016

holy fuck, I have never seen anything the obliterated. That's pretty scary, glad you are still alive

Are you sure the cases are the same for them years? I’ve been looking online (I’m from the UK) and in almost a month of looking I’ve not found a single set of cases for sale!!

Man!!! Glad it wasn't worse! Hope recovery is going well.
Sorry to see this happen to you man... Such a freak deal. I guess this is why I rebuild used bikes before riding them. Such a shame that this happened to you..

I second that.

Hope you heal up dude, but sweet Lord that is a mess of a motor. Looked like a very unhappy rod.

OP I would message this seller or have them ship to somebody in the states for you because this is a screaming deal and all you'd need is crank/piston:

Oh wow! Thanks for looking and finding this! I’ve just messaged the seller now so I’m hoping we can sort something!

Huge props for sending the link over!

It had an hour meter on it that read 26. But I’m thinking that’s a lie!

Tell me about it! Looks like the rod snapped midway and then just destroyed everything on the way round!

Damn. This is one of my worst fears/nightmare material for me. Best wishes on recovery.

I had a Yamaha YZ250 blow like that, but yours looks even worse than mine. Luckily I was just going up a hill and wasn't going over a jump. Hope you get better soon!

Take it to the limit, one more time!

Exactly.

Wow.

Nobody ever told me, I found out for myself. You've got to believe in foolish miracles. It's not how you play the game, it's if you win or lose. You can choose. Don't confuse. Win or lose. It's up to you!

Hey guys thanks for the replies already. I’m looking to buy the engine cases from the above link. Problem is the shipping is coming back at $467!! I’ve managed to convince a friend to send it from Miami if I do decide to buy, but first wondered if anyone had any better options for me to ship it to the UK? Don’t really fancy paying that much!
Thanks

Send me an email at nick_mys ‘at’ msn.com and i’ll help you out. I am from Bristol and travel back fairly often. I also have a V Force 4 from my TC250 which was on the bike for about an hour back in 2014.

Had the same “issue” on the same bike, after 30hrs rebuilt with a rabbit wrench kit.
Hotrods rod snapped, need a set of cases and a cylinder, if somebody have for sale, email me at guillo.antoine@hotmail.fr
