mxa 2t vs 4t
« on: March 06, 2013, 02:56:50 AM »
got the new mxa mag today.  they have a 125 2t vs  250 4t  vs 250 2t (all ktms) test.

I appreciate mxa writing 2t articles but I think it would have been better with a 150sx and a 300sx and the 350 4t or include them in the mix and include lap times , HP and torque charts  etc like they do in other tests for those 3.   I know they have tested the 150 2t vs 250 4t  which is good.  need to see a 250 2t or 300 sx 2t vs the 350 4t.  they don't seem to include the 450 4t anymore

They are all eligible to be raced in the same class. Why include bikes that are open class bikes ??

the 250 2t ,300 sx 2t vs the 350 4t are closer in hp to each other.  I think that would be good to compare.

The only fair handicap is none at all.
Bring back the 125 class, 250 Vs 250, and open class.  In five years I bet you would see all two strokes in the 125 class, about a 50/50 mix in the 250 class, and probably more four strokes in the open class.
The sport would start to grow again, and the manufacturers would sell more bikes, but what do I know, I have only been doing this since 1975.

Totally agree Glen. If they had a Senior 125 class again, I would sell all my bikes and just race that class. Would be the greatest thing to happen to the sport, but unfortunately, here in Aus, I dont think it will happen anytime soon. One can only hope.

Can only hope indeed. Still, I seriously doubt that 250 smokers will just flat out replace a 125. I think it has to happen eventually. 125s have been the perfect entry into motocross for such a long time and always will be. They'll hone your skills to a razor blade edge. Hell I've ridden bikes for over 10 years, a month on a 125 had me riding better and faster than all the first 10 years combined. Not to mention they're cheap and stupidly fun.

250s still do all that, but they've got too much balls for an 85cc transplant thats going up to the lites class. Way too much. The 125cc only class would be the best thing in the world.

I believe they didn't include the 150(which is still a 144), in the article because of AMA rules of racing. Many of the classes limit the 125 to 125. Not 144. Besides, don't you know a 144 vs 250 4t is cheating.   :P

If you want cheap & fast, it won't be good.

The sound of a 125 start line with 40+ bikes on it is like nuthin else in this world. Would love to hear it again.

Yamaha CT3, RT3, MX125, SC500, Toy Prius, Diesel F250 (it all balances out)

People seem to regard MXA as the ''defender of the 2 stroke".

Well, no, they vacillate with the wind / trends of the time.

IF they were serious, they would include 250 2ts in the Full, 250 MX Shoot Outs. Tell the manufacturers, if they object to that comparison, to pull their heads in. That is, if they have the balls to do that.

Show full rev range dyno charts, not refer to the KTM250SX as having 19HP more than the 250F at 8K, and calling that the midrange for the 2502t - when it's basically at / near it's top end. It has 49.77HP at 8500, the F has 42.88 at 13500. The 4ts will be soon at the door of a 2t, in HP - I'd be surprised if the factory KTMs are not approaching those levels, now. And Moto 3, is going to bring a lot more development to the 4ts. Pricey Engines, though.

They then describe the 250SX as having no low end whatsoever. What a load of crap.

I never pay much attention to the 'common' dyno chart - they mean little in real life.

MXA needs to take a leaf out of their own book - recently, on their site, with testing of a few mods on a bike, they did dyno runs at various throttle openings / revs, then compared the increases / or loss at those throttle setting / revs, then showed How much of a percentage increase / decrease that mod made at those various points. Showing that a 2 / 5 / 10 / "whatever" HP increase at certain throttle / rev settings, Can be a Big difference. Costly to do, yes, but the way it should be done, by the ''worlds best / biggest, MX Magazine".

And, they Should take the very few minutes, to try different PV Springs and pre-load effects. It makes a heck of a difference, so much so that the 250 2t will be damn near as good as hooking up on hard / slippery ground as a 250F - whilst Still having much more power, much earlier.

So, while they still do not include 'like' displacement bikes in Full shootouts, and they don't cut the crap and show  various engines operating rev ranges as they are, they continue to reinforce / create BS.

We are seeing alot of 2S back on the track. A few years ago it was all 4S, now its about 1/2 and 1/2.
Also here in Texas, the local track does 2 stroke shoot out races with strictly 2S classes and head to head stuff.
