Went riding this AM with a friend, he has a '01 YZ250 that he has setup for trail riding (pipe, flywheel weight, and some other misc stuff that I can't remember). We switched bikes for awhile so I got to sample his YZ and he was on my KTM380. No, sorry, not a 2012 model!
Anyway we blasted up a trail and did a couple of somewhat steep hills. The YZ is ok but when I get off of my 380 and on to the 250 it now feels like a 125 to me -- despite the mods to his bike that really smooth out the powerband and give it some oomph off idle. Even when I revved it up it did not seem to go all crazy like. Sure it makes plenty of power when its in the fat part of the band but my 380 just destroys whatever the tire is attached to at the time. Just too much HP except for very special (and pretty rare) situations. So what happens? you ride in the low and midrange -- in the lazy ho hum range of the motor. Very relaxing for the engine AND the rider. And if a 450F challenges you in a straight line or up a hill? Well, you have the afterburner in your back pocket.
He said my 380 is a beast. Power everywhere and insane power when it revs out. Exactly right. He said it just doesn't matter what gear your in. I find that to be the case too, I constantly reach for a 6th gear -- even when going at a not so fast speed. I guess my point is that a real big bore -- like my 380 -- really has the possibility to be a extremely easy engine to ride. It makes enough power off idle to climb some good stuff and save you when you blow a line and are stuck counting the power pulses. The 250 not so much. It really seems to make sense to me to have "real" open class 2T bikes. Yet nobody seems to want to build a 350+ cc scooter. I just don't get it. And I just am not holding my breath that one will come out in mass production anytime soon.
I love my 380. So do I look for a '07 or newer 250F at a good price to update the chassis? I don't think I have anywhere near the skill necessary to justify that upgrade. But I sure have fun on what I have now. Hope I can ride again SOON.
