All 2st 125, 144, 165, 177 You do all know there is a 250 'off the shelf'

Using that logic... Why do people bore out their 250's to 295 or 315? They should just buy a 500, right? Or is there something I'm missing...

This is what I think of when I think of a woods ninja.

He said he'd take $1200 back in January. 14 hour drive round trip for me else I'd have it.

IMO the 165 is awesome for enduros and trail riding but it's extremely hard to ride at hare scramble pace for 3 hours and not suffer from mistakes that come with a long fatiguing race on a constantly deteriorating race course. i know i could go faster on a 250 with less effort and fatigue. having said that, last season i was 160lbs, had shoulder issues, and my riding fitness was way down; hoping to be stronger this season after rebuilding my shoulder over the winter. perhaps that will make all the difference....

I'd love a modern 500 in enduro trim but unfortunately nobody builds one.

the thin line is power to weight to durability to cost, the great thing about the old (italian) 125 was the initial low price which makes the mods viable that and the fact that the bore had alot of extra wall thickness to accept the overbore.any engine performance modifications will have an adverse effect on durability of various components and so decrease long term reliability.everything has a trade off to some level but if you can take a bike of a certain weight to the limit of its components reliability at a low cost then it should out perform anything off the shelf.

I'm not sure doing this is as popular as it was. 250 2T's produce more than enough power and riders tend to consentrate on better suspension and handling to go quicker. On a 125, riders are always looking for more power, hence the kits. But 177! how close to 250 do you wanna get?

And how well does the rest of the engine that was designed for 125cc power cope before it pops.




Hey GhostRider, that video. What the..........what happened there. I've never seen anything like that before.

IMHO, the KDX was the best enduro to ever roll out of Japan and I find it tragic that the model wasn't improved upon since the "h series" introduction.

There's a saying in the auto racing community.
"It's a lot more fun to drive a slow car fast than a fast car slow".
That's one of the reasons I ride a 125.
I race MX and run Vet A. I don't win in that class, but I go pretty hard. My style is wide open throttle, high RPM's, and lot's of shifting. Even if I'm not really fast, it sure feels like it
If I had a 250, I'd probably kill my self. I don't think I could ride the style I like, with all that power, and that wouldn't be nearly as much fun.
Now that I'm a little faster, a little older, and a little more responsible with the power, it's nice to have the option of a 144, or 165.

makes me wanna sell my 360 for a nimble 125, must admit i never felt the lack of power was there as i could keep up with 250's.

oh and the only time it was lacking is on the road at full tilt, but then i was doing about 70mph and can keep up with cars happly too.

A 177 is only halfway between a 125 and a 250. It's an intermediate engine size that shouldn't be considered a stepping stone toward a 250 - it's a final destination for many of us whose style/size/strength favors a small bore over a 250.

With that said - Why does a KTM 350SXF exist? Because people don't want the power or weight of a 450, but they want more power than a 250. The same could be said about a 250 and 125 2stroke. It started with a 144, which many thought to be the perfect engine size, so it's natural to take it a step further with the 165 (or 2 steps in the case of the 177). KTM is making a killling by offering these 'intermediate' engine sizes - look at their lineup! lol.

Simply put - for me, and a lot of other guys, the 125 is too weak, and the 250 is too strong, and we don't want a KTM 200 for a number of reasons. So you can have the best of both worlds, best handling and lightest weight, and the most usable power delivery for your style. The other option is to 'retard' the power of a 250 2 stroke, but then you're sacrificing the handling and weight in favor of a more usable power delivery.

If it's not your style - then don't buy it.

I agree with the reliability issues in MOST bikes, but Husky's have seen great results with bored engines due to oversized bottom end components (read Walt's post in the 125/144/165/177 thread).

Yamaha IT 125, 175, 200, 250, 490

Kawasaki KDX 175, 200, 220, 400

Suzuki PE 175, 250, 400

There was a time when the 175/200 was a dominate fixture in the enduro scene.

KTM 200 has a loyal cult following, myself included.

There was a reason why Penton developed the 125 and 175 cc for the nasty ISDE's back in the day.

I enjoyed my 250's, but have become faster on the smaller bike. After 3 hours the smaller bike becomes your best friend!

Are crocus paper and I the only ones that are curious the ninja video?

Local guy who is apparently not wired right in the head. No idea why he likes to hide out, but doesn't seem to be any harm (other than getting run over)


I've had the guy climb out of a hiding spot (buried himself in straw from parking lot construction) 10-15' away from where myself and buddies were sitting on our bikes waiting for the rest of the group. Creepy as hell.

lol dude got worked a little. It looks like he's a white bald guy from the last second of that clip. Looks like he thought no one would cut that line. He ended up right on the fast line thru there....

its in the "kellys ongoing goofy" thread #2207

maybe its an insurance thing " i got hit by a bike!"

Thanks, saw it here first....
