Just thumbing through the latest MX Action, the new CRF450 looks, er much the same as the old ones... but Honda have given you foot pegs. MXA tried to spin that along for 3 pages of waffle about Honda listening to its customers.
However the Eurozone god blessem have been busy on their 2 STROKES ...... oh yes the Japanese may have tried to relegate the world to Hounds of the Dullsville exploding 4 strokes.... but KTM is riding to the rescue with 2 stroke range sharing same chassis and suspension as 4 strokes, the 250SX has 300cc kit and you get 125 and 150cc.
The 150cc made 40hp in 2011, which kisses off the KX250F at 38.4hp as the most powerful 250 diesel. KTM is also 12kgs lighter, hmmm, this could rain on the Japanese parade. Any parent sponsor looking at their latest top end rebuild should be rushing the KTM dealers.
Finally Husaberg has taken time out from developing its 4 strokes to focus on it's 2 strokes, gasp, the TE 450 is not selling like hotcakes. Yep and you have TM and Gas gas both producing very focused 2 strokes.... yee hah they are back

yep rebuild the 2 smoke while having a coffee,how many parents would stay in the sport if 4 strokes were as easy?
-
The Berg's look very much KTM in different cloths?
But I'm happy all the same , cant wait till one can buy a KTM 300 fuel injected.

The Berg IS a KTM with blue plastics.. That's an old model pictured, the new one has a yellow frame

Yeah couldn't find good shot of the new one. KTM seems to be the engine supplier also for the new Pursang though regrettably 4 stroke.
-
New Pursang !!! ???
-
New Pursang !!! Interest aroused.p
-
KTM 450SX powered with Spanish heritage. I am surprised the Japanese do not cash in more on their heritage, Yamaha seems about the only one so far with white and yellow bikes having been available.

Very nice.Thanks for the web address,Marc.

Thats not a KTM engine, look closely in some of the early shots & you'll see Sherco on the ignition cover which wouldn't be a bad thing although probably not as powerful as the 450SX motor

With one small exception, the Bergs get the top of the line twin chamber WP forks and matching shock whereas the KTM is relegated to the entry level WP's. I haven't ridden either of the bikes but I know a lot of expert/pro class riders here in Victoria that say it is enough to warrant paying more coin for the Berg just to get the suspension. There are other small tweaks that Husaberg do that (from what I'm told) are enough to make them feel like two completely different machines.

Hell I would buy a Berg just for those fork protectors. But make mine a 2 stroke. If you ride a modern 250 or 300 2 stroke they are really the grunt kings on the steep trails, you can use the torque on the edge of the power band, rather than have explosive wheel spin and flame outs, though admitedly the 4 strokes I have ridden have all been converted MXers.
MXA said the new Pursang was KTM powered, KTM or Sherco it is still a cool thing.
-
The berg has better forks than the ktm but the shocks are the same. The 2 stroke berg uses a lower compression piston than the ktm which explains the smoother less explosive power delivery.

John,
I was under the impression that there was significant changes to the power valve operation with tuning to the carbie to match. Of one of the riders I spoke with said the difference between his early production 2011 KTM and his new 2011 HUSABERG was chalk and cheese. Kinda hard to explain when they share the same base chassis & engine. The other thing was that most said was that KTM dealers had lost touch with the average Joe because KTM's really sold themselves whereas Berg dealers were a little more hungry and took the time to understand true customer service, particulary post sales of the bike.

I think as KTM moved away from being a dirt bike maker to selling road bikes and associated trinkets, then the focus of their dealerships changed and became a bit more Hollywood. Bergs tend to be sold in the smaller niche dealers who are more focused on dirt bikes. So good reason to buy the Berg, Sherco, Gas gas, maybe Husky.
-
I'm not sure of those other changes bahnzy, I work at a ktm/husaberg dealership and am only aware of the things I mentioned but the only way we found out about the different pistons was when we were rebuilding one.

Another writeup on the KTM250 .
Both have contiual improvement and the 2012 years end outcome will be interesting results for the market .. :P
Roger DeC still in the Orange seat this coming year ?

You don't have to convince me ,........ been on them for the past 15 (or so) years .
Maximum ride time, minimal hassle ,........ when compared to modern 4str grenades
Only normal maintenance / consumables & a piston kit every 2/3 years ...... too easy ;D

This CRF engine is on Trade Me at the moment, comes with optional HRC oversize crank case breather ;D ;D

shit doesn't look like much is salvageable there Marc !

Aah Hoony, you missed the obvious.... along with the grenade cases there will be a good CRF chassis just begging for the spare CR500 motor you have lurking some where....

On the subject of late model 2 strokes. I have had the pleasure of owning a 300exce 08. after approx 3000k's i pulled the top end off it, to fiind that the bore still looks great, cross haching all good no nip marks and the bike runs like new in any case. After writing the part number of the piston, I put it all back togeather and still all good. The question is should i put another piston in it and give it a light hone, or just leave well enough alone. Its only a social ride bike, but i tend to give it a bit...

At 3000 km's put a piston in it before it cracks the web off it and it will cost you a bomb. A hint with Katoh's, if you don’t have to pull the head off, don’t. As they get on in life there has been more than the odd owner that has struggled to get the head to reseal onto the barrel after it has been removed. If it isn’t leaking and it doesn’t need to come off then don’t take it off.
As you have already checked the piston to see what grade it is, the other point to make sure is that you measure the best part of what’s left of your base gasket as they are selective fit. A good KTM dealer will ask you what thickness gasket is fitted, a not so good dealer will give you what’s on the shelf.

Try finding a spare CR500 motor these days for a reasonable price, been a few too many CRF450s needing new engines.

The story I got years ago was that the 2 strokes with power valve and water jackets and pumps were almost as hard to rebuild as a 4 banger so that's why everyone went that way.
I guess the newer gen 4strokes are very highly strung and need lots of TLC.
I also figured that it was time for the 2smokers to make a come-back as that will give the kiddies a new focus and they will dump their CRFs etc... like --because they are sooo yesterday :D
