PulpMX stopped by RV's Farm just after he clinched the 2012 SX Title and the focus was switching to outdoor prep. Stay tuned after the credits for a raw lap around RV's outdoor track on-board with Adam Cianciarulo on his Super-mini.
Some sick laps by A.C. at the end 👍🏻 Not sure what cc that was, but I don’t think you could have wrung more rpm out of it! Awesome video! And I know it’s ten years old lol
That was right before he crashed and ended his 2012 season. RV's 450 titles was the end of the golden era of motocross. RV is in the top 5 greatest riders of all time, maybe top 3.
Btw I know that's AC on the two stroke I have like 20 emails saying thats AC! not RV. I never said it was RV I just said he is killing it.I should have been clearer Adam is killing it!! That's what I miss about the twos you could tell who was pushing their bike by the sound.Now they all sound like lawnmowers and besides panic revs in mid air. Its hard to tell how many rpm's their turning or how hard their pushing it.
Don't get me wrong I am not biased I own both a kx 250 and a xr 500.As well as riding my sons 450f love them all! I have worked on pretty much every race bike made. I rebuild ,port ,polish engines as a side job.The biggest advantage a two has is dependability and low cost maintenance.Its cheap when you don't have valves to rebuild.I can full rebuild my kx for about 200 bucks (sleeve it myself) it cost me x6 that to rebuild my sons 450f. Sorry but 2's are just more efficient pound for pound.
You sir are wrong. There is the SX 125 which is also available, and then there is an SX 150. Its not Just a big bore kit, its actually a different bike. Although it has the same frame and weight, but so does the SX 250. They are all 200 pounds dry with the same sized frame. So all I am trying to say is that you are wrong. the 150 is not just a 125 that comes stock with a 144 kit. it is actually a 150.
But, he has 2 supermini's one that was a kx100 and one that was a kx85 he mostly rides the one that was a 100 but in the Monster Cup he rode the one that was a 85..
wow, youtube agruments are quite entertaining to read. Anything done to a bike, that exceeds the out of box stock performance of the bike is a modification. Boaring and stroking of a bike is a type of modification, just like putting a pipe on the bike is also a modification. Just depends on what type of modification your going for, and what you want out of it. Factory bikes like Adams 85 or Villopotos 450 are modded far more then you can imagine.
It takes more skill to ride a 2 stroke fast fours have a smoother powerband allowing more power to the ground.A really skilled rider can do that one a two stroke it just takes good throttle control.CC for CC the twos still put out more hp I smoke my sons yzf250 on my old 98 kx 250 its not even close. My point is the AMA should have gave the riders a choice not force them to ride a certain bike.A happy medium can be found say a 300-350 two vs a 450f would be even and IMO make for better racing.
That is how you ride a 2T. Notice the finger on the clutch at all times. Pin it, get it in the powerband, tapdance the shifter, and use the clutch to modulate traction. Too bad he'll be on a farting 4T in the near future. If only KTM would put him on a factory 250SX before he forgets how to ride a 2T.
cc to cc means nothing when you compare different engine types. The class structure of a 250 smoker vs 450f is based around the engine's mean effective pressure, or it's capacity to do work independent of engine size, and these two bikes are similar when looking at MEP. A 2 stroke will make you a better rider, I ride one and love it, but it is not faster than a 4 stroke around a track to most riders. The point of racing is to be the fastest right? Why handicap yourself for the sake of nostalgia?
I have nothing against four strokes besides the fact the industry forced them on us.They are alot more expensive and much harder to work on pound for pound the twos are still a better value.Also RC won all 24 moto's vs only fours two's had already been pushed out by then.Its the rider not the bike I just pointed that out showing that twos can compete. I own a 450f and a 250 two I have spent tons on the four on rebuilds and valve jobs.I rebuilt my kx250 for like 150 bucks in parts.
