Yes, 125's are fun. But even me, who don't ride much anymore, I just watch the kids go round and round. But when I do, a 125 just doesn't have it for me & I don't even jump anymore. Granted I love riding ours and it's a blast. But the 250 just gives the feel of raw, arm pumping, neck-snapping, seat-of-the-pants feel vs a 125. But my son is the same way. He loves riding the 125 to play on because it feels 100lbs lighter and he can really rip on it. But in a race, he wants the 250. He doesn't have to rely on sweeping a turn perfect and full bore to keep up his speed to pass someone. He can take the inside and have the power rip out of it. That's where the 4T 250 has the major advantage & why it's BS to put 125's against them in lites and say they're comparable. Like I keep saying, A 250 is a 250 is a 250. I also don't believe the CRF150 should be allowed in the mini or supermini classes.
It's like driving my truck then getting in my wifes DD. Her little 4 banger just doesn't have it. Until I get her other car done. 450hp is gonna be nice
