Packaging power - 2T Vs 4T

[Freakshow]

nimmo,  i have already dinged the exhaust, been told its the same one from current back to 99 so thats a blessing, just have to hit ebay and see what turns up.

Did HAd a punch out on the new yam 450F - 2010 with the reverse barrel, bloody trick bit of gear, handles really really well, can see them hitting the pointy end.  but that aside as an old fella in the end i  cant justify the expense needed to run these new 4 bangers, i can run a 2ee all year and never open the oil filler if im tight, and know it wont be a problem.

NIMMO - CHOICE WAS EASY - reackon i've had every YZ250 from 95 ( or whatever the one was with the light purple frame - to 02 and they were prity much the same bike, never had one lunch and always 4 kicks tops. 

The 4 banger liked to stall out and would leave you dry kicking for half a lap if it didnt like the way it felt.

MA just had a rule change that now allows 250 2t's to race in the lites class in the MX Nationals, and word is that they extend this rule to state and local competition in 2011.
Finally a bit of parity in the classes.

I raced a 2000 yz250 and a 2003 yzf250. What i notice, is when you nail the throttle out of a rough corner the 2 stroke rear end bucks and jumps around, whereas the 250 fourstroke is smoother. Also when nailing it hard towards a jump the fourstroke rear end drives smoother and straighter, which helps to pick your line. Also the hit of the 2 stroke is more physically draining. These traits make the fourstroke better for me as an older unfit mx'er.

The road racing Moriwaki MDH 250(CRF 250 in RS 125 frame) was allowed to go to 300cc to be competitive......................................with 2T 125's. Was only fast in qualifing for some strange reason and would finish at the back end of the top ten 25-35 seconds down

[Marc.com]

The MDH 250 is about to become the Japanese standard as 2 stroke 125 and 250 racing stops. Like the NSR80 which was killed off in favour of the NSF100 even though the 80 is much faster the 100.

Expect and NSF250, then they will kill off the 2 strokes then sponsor an NSF series just to make sure the 4 strokes are the only ones out there.

So does that mean the 2 stroke 250 this year we race agains the 250 four strokes ? in mX and Dt moderns

Tis the Honda way...............................

Freaky the rule change is just for the MX nationals.....with a view to bring it in at state and local level next year.
Parity in the lites class (250 4t and 250 2t ) is being pushed hard in the US and on the surface that makes sense But , if this follows through to Australia, what do we do with the 125/150's ?
They would be pushed from the lites class, but there is no other class for them. They can't be rule out altogether as the are VITAL for young riders transitioning from the mini class. Do the clubs have to introduce another class to an already packed race day ?

Lozza your spot on, I recently saw a Honda promo video about their racing division. The Manager stated wthout a stutter that "Honda is not a car company or a motorcycle company, they are first and foremost a engine company and a fourstroke engine company at that"
If they had their way everyone would be on a fourstroke.......cause that's where the money is.

This is from the US GNCC racing series on the weekend.....on the Can Am GNCC racing site

In the XC2 division, Jason "UK7" Thomas took advantage of the new rule, which allows 250 two-strokes to compete with 250 four-strokes in the Lites class this year, riding a Monster Energy/FAR Racing/ Andrews Cycles-backed YZ250 two-stroke to a first place finish in the division.

Last year's champ Factory FMF/KTM Off-Road's Kailub Russell went down in the first turn, but recovered to finish third, despite tearing the skin off his hand on the choppy course.

"I just washed out the front in the first turn, but going into the woods I was already in third, so I was pumped about that," said Russell. "The skin ripped on my hand and it was pretty bad after that.

Jesse Robinson, riding a two-stroke KTM, capitalized on Russell's injury to claim second.

"I was behind Thomas at the start but I kind of pumped up, and then Kailub caught me," said Robinson. "Later in the race, I just picked it up and moved into second."

Meanwhile, Kawasaki rider Josh Weisenfels and KTM-mounted Jake Korn rounded out the top five.

John Day grabbed the $100 Motorcycle-USA.com Holeshot Award at the start of the XC2 race.

Open A Rider Jordan Ashburn claimed the Top Amateur Award.

The second round of the Can-Am Grand National Cross Country series, The Maxxis General GNCC, is this weekend, March 6-7, in Washington Georgia.

"I'm stoked to get the win and get off to a good start for once," said Strang, who has had bad luck at the Florida race in each of the last three years.
