I can see these working ok to well in local very small markets with no Mod Class where they are allowed to run with stock bikes. AS long as the competition is also running stock and not modded bikes. These bike will pull alot taller gears due to the torque of the 4 stroke. The two guys that are pushing them on this thread have something to everything to gain from them being suscessful.

Ncc, Most of the items you listed my stock 125cc had on it. I cant say 100% compliant but most were pretty similiar and the 26mm Mikuni was stock as well. 20mm head pipe shiat I cant exhale out of something that size little alone a 125cc 4stroker...

Yes your 110cc pretty much sq bore might rev a little quicker, but you are also giving up torque with the shorter stroke/cc's that I had. All I was trying to do is compare what I have ridden to what your trying to push down my throat. I dont see you making a huge amount more powwa then that pit bike.

Ok, let me ask this. About how much horsepower does a STOCK KX65 and KTM65 make? Someone said a modified one can make 17 HP? I ask this because my son wants a 65 mx bike. He currently rides a stock KLX110 which makes about 6 HP.
ALso, I posted on this thread simply to let people know there is another option for the 65 class. I own a Pitster and a KLX and love both. I'm monitering this thread simply to gather information for the purchase of my son't next bike.

Ya know Jamie.. some said up earlier in one of the post, about looking for change. It happened before in another segment of the Mx market, and it may, or will happen again. AND.. what is the end result 10 plus years later? Way, Way, reduced numbers of racers, and Much, Much more expensive sport.
No thanks. This site caters to the thumpers, but that change 10 plus years ago is crippling/crippled our sport. From the grassroots, local level especially.
One of the guys said their top end re-dos, were the same as our 65. Under $100. I call BS on that one. Post the cost of the piston kit. Gasket kit for it, and the amount of time it takes to do the job, which will help correlate to the amount of labor cost.
I'm not at all for change of going to the 4 strokes in mini racing. If they are competitive, give 'em a couple of classes. And.. I know all the dynamics of 2 stroke and 4 stroke engines, and why it produces this or that. So the apologists can save the explaination. But, I say BS also to the displacement rules. Produce a motor straight-up equal in displacement 2 or 4 stroke that are complete equal cc-wise, and then let's race. If a 4 banger at 65 cc's can't make the same power as a 2 st at that size, well too bad. That should be the only dynamic for racing any kind of motor, in any sport.
Give me a 4 stroke engine equal cc size you plan on racing that class in, like 65 cc's, and if or when it produces the same power, then I'll be impressed. Otherwise, you're right.. We may be headed down that path we took 10 plus years ago with big bikes, and this time the minis will be done, and racing numbers then will be near zilch!!!! Except the elite rich folks. Then what do we have? The NHRA....

You do know that the two strokes days are numbered no matter what, if we market one or not, the EPA has those things on the endangered list .
I am also not shoving anything down anyones throat! Buy or don't, plain and simple.

what model pitbike are you referring too stock?? I am very deep in the pitbike industry and would love to know a 125 that came stock equiped like this??


I do not see why all the hostility in this thread??(not aimed directly at you) the kids riding them now love them,, the ones testing them love them, is that not really what it is all about, I think MINI dads are really what ruins the sport, not dads with kids that race, MINI dads,,, they know who they are, there is a difference.

QuickSilvers said:

wait,we were mod in 09, 2010 is a whole different ballgame.
Stock and mod!

Well, good luck with it. Ultimately, these conversations go nowhere. Those fot it, and those against. Down the line, the bike will either make it's mark, or not. Racers will race what gives them the best opportunity to compete or win. Time will tell. If it's capable, it will make it's mark. If it can't, it'll fall flat.... Pretty simple!

Btw.. I will remember to ask Parker Fleming about the bike this weekend. I'll report back EXACTLY what he said.

Your right, its either put up or shut up no question about it, thats what makes it such a challenge and so fun!! We will continue to do all we can to "make our mark" Remenber when people laughed at KTM? I do! All I know is its great to be able to go out and compete with a bike at such a affordable price!

Tell Parker, his mom and dad, Matt and Matt Jr said hi, he is a great kid, we had alot of fun watching him pound the bike in Branson, also too bad the lead ban screwed up all our plans,  I think he would have done well.

Mabey you didnt notice but i didnt start this thread , just jumped in to discuss the merits of the MXR
This bike is a option that may work well with some and not so well with others

The engine configuration is very similar to other pitbike motors,yes
but internally its configured more like a modern four stroke
"over square" and we can set it up with more powerful heads

One the subject of the suspension , the components are the resprung/valved versions of the same system use on adult pitbikes and i the 3 years these have been out on bikes with full size grown men beating them i have never seen a report of them coming apart

MXR is a very very good overall chassis and it has a strong motor
we sell the top end gasket sets for $15 , piston kit $60
thanks for your interest in these machines

another comment that was interesting is the progression of the MX and AMA into 4 strokes and it raising the cost of racing
on this i agree that the AMA should have been more compliant to 2 strokes and keep the 4 strokes at 400cc or some other leveling methods

but this MXR program is very different and quite economical
your looking at a 2k bike with an engine that can be REPLACED for $500
im not 100% sure of the current retail prices of the other youth MX bikes but
it seems like you could get a race bike and a practice bike for the price of ONE of the other brands

I believe the Kawasaki KX65 is the least expensive 65cc MX bike. It's MSRP is $2999.00. The KTM and Cobra 65's are more expensive.

Wandell said:

I agree, you will find the cobras, and KTMs are near and over $4000!!! That does not seem like cost effective racing for a two stroke? at least not for a kids bike.

ncc said:

I would say spending $4000 is cost effective if the kid is a serious racer and it allows them to run at the front of the pack.

I would also say that spending half the money for a slower bike is OK if your kid is not competitive or is riding just for fun. (Or they are so good that they can win on anything!)

My son is in the second group and rides a used KX65 that cost me $950. He actually came in second place (beaten by another KX65) in the last XC race. At his level and the type of racing he does suspension and bike weight is much more important then power - you can't go fast if you can't hold on to the bars.

I think one thing that needs to be considered is that some younger/less experienced riders may be more comfortable and able to ride faster on a 4 stroke than a 2 stroke.

Wandell said:

Very true, my son Rayce finished the local championships third his first year racing becasue he was better at the four stroke than the two, He was smoother, and could think about the track more and the shifting less, his results improved overnight.

the MXR 110 E is quite possibly the best overall youth MX racer for a beginner / novice that money can buy

That's the model with the semi-automatic tranny, correct?

T Bolt USA said:

Shameless...

Polini is claiming 15hp out of their 110cc 4 stroke only legal in Mod class bike (Same as your Chinese built bike, just because someone claims its legal in stock class doesn't make it legal until its printed in the rule book)...Still no claimed power numbers....huh?

Wandell said:

Look in the provided link...Yes its a semi clutch or is it...Says in the top text that is a semi and down below it says its manual.

I find it funny, that the bike has to be marketed in such a way. If it blows up the market then it will sell its self. Must not be selling like hot cakes the price keeps droping....

Hell if it gets much cheaper, these will be throw away bikes...oh wait..

Quicksilvers, I really think the Lead Law ban earlier this year hurt the sells of the Pitster MXR, just like other youth bikes.
