Kid qualifies for Loretta Lynns on 85 CR250

I hope some factory realises now that there is a  market to produce simple strong reliable easy twostroke mx bikes with steal  frames

They do, KTM and Husqvarna

They do but they make a shit load more money selling those shitbox modern 4 strokes and the huge amount of parts required to maintain them. Their dealers sell more workshop time because people wont maintain them themselves and aftermarket 4 stroke heads , cams , pipes and carbs etc are a shit load dearer than 2T ones especially when there are 2 mufflers to replace .

Bike manufacturers are run by accountants NOT enthusiast and common sense and passion is irrelevant to those pricks .

Good luck to the kid , he is fast , humble and a credit to his generation   

While I get your point Bill I think that the modern 4 stroke bike is a great bike and Honda (can't speak for the other brands) has always been 4 stroke aligned. Can't see anyone on a 2 stroke doing the jumps they do in supercross on a 250 two stroke? I hear a lot of storey's about the cost of 4 stroke bikes but having just done a top end rebuild on my 2010 CRF 450 it was all at very reasonable prices. give them good oil and they will run for ages.

I do agree he is a great kid and wish him all the luck in the future. what an ad for a well bought up kid and not a Red bull in sight!

Just imagine how good he would be on a decent bike aka a 1985 Suzuki RM 250?

Now for the bad news ........................we are completely devoid of excuses from this point on. There would have been some funny looks at scruineering, but a awesome effort.

It's not the bike, it's the rider!

I reckon a 350 or 400 two stroke would fix that. I keep thinking if they make a medium big bore with four stroke characteristics it would be a big seller. Like a longer stroke and smaller bore or taming the hit with a bigger flywheel etc. my yz/ wr is smooth and pulls from low revs which I assume is due to the flywheel weight.
Back to the young dude, I love what he did and his attitude. What a champ!

That could be because they are a 250 2t up against 450 4t...how would it end up if a ktm 150sx vs'd a crf 150 or a ktm 250sx vs'd a ktm 250sxf

   Somebody better tell Chad ,Ricky and James that you cant jump 2-Ts', seem's that what they preferred on their practice tracks !!! or Travis and most of the freestyle blokes ,or maybe they could just bring out a 450 2-T  with modern technology  to 'even' the field

I remember back in 2004 when I was riding Saturday Gippsland Series in the vets at Outrim, my current bike was broken down and I had to ride my RM400C 1978.  I pushed it through scrutineering and the laughs that we had when the boys looked it over - I told them "this is a trick works bike, it has 2 back shockers, not one, air-cooled, no radiators and special drum brakes for railing berms".

I got third that day out of 17, and 16 of them were on moderns. 

[STW996]

as usual you blokes miss the point on the 2 stroke thing. if they are so good why are they not racing them in any open class race? free style is all about explosive power and that the 250 does have also a lot lighter than a 450.

anyway my point was taken from what RC was saying as a commentator during the supercross.

I love 2 strokes myself but the 4 stroke is now just a better race bike.

sorry to have got off thread.

And still a little off-track, Having owned modern 2-strokes and 4-strokes, the main benefit I see with the 4-stroke is how wide the powerband is, when the 2-stroke goes off the pipe it's all over but the 4-stroke just keeps making power.

John that merely the tuning of  engine , also no development work has been input from Japanese manufacturers from the mid 90's on 2 strokes. CC for CC the 4T's have a traction advantage which over comes the HP defict.

Yeh a similar thing in Superbikes back in the 90's when the 1000cc V twins had a firing interval that allowed the power to be put to the ground compared to the 750 inline fours.

Recently Motocross Action ran the 2012 KTM 250SXF & 250SX on a dyno, at 8,000 the SX had the horsepower lead, at 10,000 the SXF had double (!) the horsepower of the SX.

But then at 6,000 the SX is double the power of the SXF, so as you say, tuning can 'rob peter to pay paul'.

[TM BILL]

All this talk of horsepower , how many people actually racing either modern 2 or 4 strokes make use of most of the power available.
