Was just looking at the racer x sign of the lap times thing, and Blakes fastest lap of the first 250 moto, was just under a second of of RV's fastest lap in the first 450 moto, and RV set his fastest lap of the race on lap 4 of the first moto of the day. Blake set his fastest lap of the first 250 class moto on lap 15, so the track would of been alot rougher than when RV set his time. So, since the difference is so little between those guys best laps, and the track would have roughed up a fair bit, how comes 250 2st's aren't competitive in the 450 class, when the 250 2st should be able to set faster times than a 250f since it makes more peak hp, more torque, and is lighter than the 250f?
450 moto 1: 2:13.363 4 2:17.697 Ryan Villopoto
250 moto 1: 2:14.211 15 2:18.103 Blake Baggett
And in Moto 2 of each class, the difference is a little bit bigger, but still not much.....
450 moto 2: 2:14.639 3 2:21.353 Ryan Villopoto
250 moto 2: 2:16.616 5 2:21.925 Dean Wilson

Also, a track with a Up-Hills and Sand-Sections favors the 450s; yet, that extra mass had to be a bitch in those REALLY rough downhill/corner-entrance sections that turned into "Black-Holes".
Blake was ON FIRE and RV was Sick.
There's a lot of "Give-n-Take" here; however, it all adds up to the fact that the 2 Kawi riders in question are the Fast Guys.
Imagine Blake on a Fo-Fiddy.
I'm jus' sayin'...

Go pound out 15-20 laps on a 250 two stroke and get an average time, then do the same thing on a 450F or even 250F. Your laptimes won't drop off as far on the 4 stroke.
The other thing is the track conditions won't favor a 2 stroke if you have 39 4 strokes on the track.
can you imagine trying to get a top 35 start on a 250 against 450's?
2 strokes don't need it, but like it for power and reliability.
same reason i raced a 2 stroke 250 against 450's a couple years ago and got smoked to the first corner
(i'm a very good starter btw)
Also, the modern 250 thumper puts it to a 2-stroke pretty damn well on a lot of tracks.
Pit Row
I've switched between 2 and 4 stroke multiple times over the years and by far the hardest thing to compensate for on a 2 stroke is traction. They just don't hook up anywhere near as well. People say a 250 2 stroke will beat a 250f (all things being equal with the rider) but imo that's greatly dependent on track conditions. If it's fairly heavy loam then yeah of course, a 250 2 stroke can put all it's power to the ground without too much wheel spin. But almost anywhere else and I'd go with a 4s.
He gets pulled out of corners... which is not a problem on a practice day where you have the whole track to yourself, but what if you get your line taken, or it's just tight, you get pulled...
You need to be on the fastest bike you can or at least have room to move...
I don't thing displacement(for the most part) or number of power strokes really made that much of a difference(in general). With a track that rough it is more about line selection than just about anything else. Finding a line that kept the rear wheel on the ground and driving forward was the trick of the day. More so than your average track methinks.
Post a reply to: Sign of the lap times, why aren't 250 2st's competitive in the 450 class?
