HI, anyone remember what the HP of a 250 was back around 1988? Was it pushing 45+ like they do today?

thanks.

Nope, more like 41-42 hp and no where near the broad power band of today.

I'dbe surprised if it was even that much.My 92 and 94 CR250's made around 42-43 and absolutely slaughtered my 88CR.

I remember when the 84 CR250 hit 40 HP. It was hailed as a rocket.

It was also a bit of a grenade.

The biggest improvement has been the breadth of the power... there is much more area under the curve.

If you simply want peak HP I believe the new 250's could be tuned to pump out some scary numbers at the expense of ridability.

Maybe a Husky 250. :nener:

I think I heard the 06 KTM 125SX was hitting like 37 off the floor.

That's a big peak number for tiddler.

A friend of mine has an '89 YZ250 that he still rides (it's in perfect condition - better than new). The engine has been bored, ported and is always in a proper state of tune. And I hate riding the darn thing!

Not only is the throttle sensitive, but the power comes on suddenly, all within a very narrow power band. It's like riding a bike with a switch for a throttle. Without fail, every time I ride that bike I hand it back to it's owner with one of my body parts hurting or bleeding (or with real bad poison ivy - but that's a ugly story).

Anyway, the owner of this rocket powered sled is always eager to point-out that his 16 year old bike makes just as much horsepower as a new bike, which I'm sure it does. But do not confuse quantity with quality. His YZ is evil and a real handful to ride, unlike a modern bike.

Well, the 87 YZ-250 I had dyno'ed at 38 which was typical for that period as I recall (I know many mags listed around 40 for 250's then but that must either have been at the crank or advertising hype; I don't recall any stock ones getting 40 or more at the rear wheel on a dyno but I could be wrong...). Don't know what my '89 had.
