How much is a full blown race motor for a 125? (seriously asking, I've never had or raced a 125...
Same money spent on a new Husky/KTM125 will get you at least 42HP. No bolt on's
I heard Emig mention his 125 had 39HP last night so I'll assume 40HP is enough. My XC engine has 38HP.
You'll still spend more on a 4T once you add 12 months of tires, good enough to race on. Both require oil. Time is also of value.
By the way, I'm not bashing the idea of a 125 class, I'm just putting things into perspective for people that are quick to say, "it will be cheaper!"
450 needs oil and oil filters. and a lot more maintenance time.
What's a piston ring worth?
You don't really need to spend anything on the new 2T engines IMO. Set the squish up and away you go. Useable power is way under rated.
The question needs to be. What are they spending on 250F engines?

I love 125's and hope they never go away. I know for a fact that if I didn't grow up racing 125's I would be much slower now. It's a shame that 250f if superior in performance in every way.
A 250F is still more reliable than a 125 with the same rider and modifications. But 250F mods and rebuilds will cost more (albeit less frequent). This is really simple stuff honestly.
You saying the torque, and weight of a 450 wears a tire no quicker than a 125. Ya trippin! It's not even logical.
More oil changes, oil filters, valve clearances, tire changes. How quickly can you tear a 125 down in comparison to a 450? By the time a lap top loads I can finish tuning my 125. All takes more time.
The comparison needs to be between a 250F and 125 anyway. 250F' are grenades. If you're rebuilding a 125 frequently I'd suggest using better 2T oil and fuel.
We going to equate for engine drama's in the budgets? Or just hope for the best.
How's those 450 Honda clutches going?
I have both ATM. I have raced both. I'll agree to disagree. Although, I think you're trippin as well. 450's destroy tires.
I also ride my 125's off road. Where I live, you're either going up or down mountains. The clutch cops heaps more of a flogging in the bush.
I raced Rotax 125 in Karts for 5 years, won 2x Australasian titles. Never blew an engine or replaced a top end. Actually, never spent one cent on the engine in that time. No gears. That biatch revved at a constant 19K. "Go well. Go Shell".
WTF are you blokes doing to your bikes?
I might grow but I'm not sure about it.
300cc bikes are not as common as 125's
At the Dutch Nationals there are 125 races already, no 300's.
To enter this class you have to purchase the bike which is pretty much useless for other races.
Just needs some more time maybe...
And shortened Top Fuel to 1000ft track.
Let's compare a $200,000.00 Pro Circuit Kawasaki 250F to a new Service Honda 500. How's that for stupid? Go put 100 hours on each of those and get back to me. Crickets....
Pit Row
That was one expensive bike!!!
I compared a 125 to a 450 because with their logic a 450 is un-affordable to race and 125's are the topic at hand.
I'd like to see KTM powerparts offer a head/ pipe/ cylinder kit for the 250sx that had lower peak hp but a much broader and smoother powerband, similar to a 250F. That would be a compelling package and could run for years. Low noise, etc...
But for amateur and younger classes the use of 125's makes more than sense.
Now the 1st will come up but that's there already you can race it and only your own stupidity can stop you!
That's not right as long as the large 4 Japanese Manufacturer don produce at least a newer generation of 125's that will not happen. Due to the stupid AMA rule that a 125 can compete in a 250f at the same time it is obvious what will be selected.
Maximum Power is sort of equal at least with some $ you can make it.
The huge difference is the gap in Torque the 250 produce a ton of torque.
But when it comes to power you don't have to go to the larger Companies like PC or others they are a huge Sales & Marketing organization with one target "getting your money" And as long as you don't have the right connections you will never get the same porting job done like you could have with personal links.
I went through those things with my 125's when I raced, watch out for smaller specialized tuning companies the might listen.
Had the experience in Europe, through a friend who knew a Tuner in Netherlands I got my engine done every year for less than 500USD and it was night and day.
I think nowadays you can get it done for about 1000$ at the most.
I worked at the Kart shop I raced for, running the Dyno. Feel free to tell me how it is though.
Valentino Rossi's mechanic's son raced Comer 90's. He used to get us to build his sons engines.
