KX af project or not?...

[nom de guerre]

Yep, I will put the whole engine/fi/etc out there for a lil while and see if there is any sale or interest... If it sells, then I will go the KDX 200 engine route. It will be a limited time that I try the parts sale thing, then I will just bolw the bike out cheap to get it out of the garage. I already got new plastic and graphics for it... Thing is stinkng up the garage next to the 125 & 250!!!

Me being the nice person that I am (  ) I let my neighbour use my steller stand for what was meant to be a few days until he could get rear tyre replaced. Ended up being over a month of his 250F making me look bad

[TMKIWI]

Go the KDX route.
You have the MX bikes covered so might as well go for a nice woods motor.
I have had a KTM200 and they are great engines but for a cheap play bike I would have the KDX engine.

[nom de guerre]

 Yep- I am going the KDX route with the chassis.. will be a great play bike for sure. The 4t blow up vids have got me freaked the hell out and I want the 250f engine GONE!!!

[Stusmoke]

Id say if you don't run it it wont blow up, but this is a 250F engine we're talking about...

[2STROKEREVOLUTION]

KDX200 motor would probably be a great, affordable motor. The KTM would likely be more powerful and modern but cost more. Either would be cool.

Is it too late to suggest a KTM 380 motor?!

[2STROKEREVOLUTION]

Good stuff Sachs... I have had a deposit on the Ossa since the day of the press release. Latest info doesn't sound to promising however.... something about GG engines, etc. Maybe the Jota....?

I heard some rumors of GG engines coming out first. Which would ruin the benefit of the Ossa. Jota is questionable on if and when it will be available at this time. Not to mention if it will be any better than what is out there now. Best bet is a current TM or Gas Gas. Both are killer bikes. TM now has KYB forks and their own Works shock and supposedly better motors than KTM. The Gas Gas has legendary handling, great motor, great looks and a trick air filter for 2013.

^^^ yeah, rumour is that the Ossa won't be out any time soon... Kinda rots, but I half expected that when I put the deposit down. Funny thing is, the Explorer model is out now, so I don't know what to think. I will still get one when it comes out(if ever). I love the TM's and the '13's are amazing... I may snag one in spring to book end the KTM. I really like their 300...

Nope, not too late at all on the 380 suggestion! I had a '98 back in '98 and loved that engine.. Until I find my transplant engine, I am open to possibilities. The Kdx 200 engine would be a great engine for the easy days though....

That is strange about Ossa. They showed a complete bike like a year ago and no production expectation. The Explorer, meanwhile, still doesn't have a single real photo on their website, just computer models, yet people have them and are riding them. Weird. The Ossa Enduro looks sweet. Full Ohlins TTX and semi-Direct Injection.


The KDX 200 would be a great trail motor. Nice and easy. The 380 vibrates more, not making it the best slow trail bike. I just love the power. Torque down low like a 300, and the top end of a 500. It'd be cool to see an awesome KTM engine in a great frame. But, whatever you make will be cool. Can't wait to see pics.

Good luck with the Ossa or TM, both are great. Or there is always the Gas Gas Guillaume! So sexy...

Why use the KDX engine? Why not a KTM 200 EXC engine? I understand the KDX would atleast match up brand wise but the KTM engine is a more modern and more powerful/tunable motor.

The KDX is an awesome woods engine. A lot of people bash them. But once you own one and spend some time in the TIGHT woods on one you realized why Jeff Freddette raced them for so many years. Really the worst thing about a KDX is the suspension and that's why the KXDX conversions are so popular on KDX forums.

[SachsGS]

The KDXs were very nice bikes but they were built to a price - lower spec brakes and suspension etc..

There is an Ossa Esplorer for sale on Ebay.

Ditch the 380 and wedge a 620 Maico powerplant in there.

Exactly, that's why I said KXDX conversions are so popular. You use the great engine in a better chassis. I was going to build one from mine and then I ended up selling it first.

[Stusmoke]

I'd love to have a KDX as a play bike. When I actually want a play bike that is. Maybe in 10 years time when I'm not as insane as I am now but until then I'll keep on pushing my limits on my 125.

I still definitely want to see this bike though. Make a new build thread

THAT would be indeed interesting. 620 good god thats crazy.

Hey a quick and really unrelated question that I have: Why do the 250 smokers only make power up to roughly 9000 RPM but keep on revving until 13 grand? Not meaning to thread steal here just a random question I had that seemed silly to make a new thread over.

[cnrcpla]

I don't think a 250 2T can hit 13k rpms. I could be wrong, but I believe the max is about 11k if your pushing a really modified motor if your lucky. They usually top out at about 9-10k depending on the year/make/model. 125's can push 13k I believe, but those suckers rev.

Ok my bad, but what makes them just stop producing power? It seems pretty silly. The 2013 SX250 literally makes zero horsepower after 9800 or something
