Yes in fact I did just compare my hammered crf450r with a ported 500 2stroke for climbing mountains…

Maybe this seems unbelievable to a sea level track monkey, come to east Idaho
where the parking lot is at 5500′ and you spend all day riding 6000′-9500′ elevations.

It’s no secret that thumpers hook up better, don’t bog down anywhere near as much as a 2s and don’t suffer anywhere near the power loss at higher elevations. 4strokes needing little to no run & upshifting mid climb vs the 2stroke’s monster runs(not always an option) and constant downshifting = advantage 4stroke.

The big dogs in the mountains are thumpers.

Some of these revised off-road weapons cost as much WMD’s!

did you just compare your 450 with a ported 500 2 stroke? i didn;t think so, no one could be that dumb

Those 2 things u mentioned as “evil”(JMHO), are there to improve driveabilityon the street (key word:STREET) and nothing else (unless) the diaphragm actuated door on the air box closes again at high rpm(very unlikely), then it really becomes a restriction.
Most probably easely disabled like people used to do it on the Honda RC51.
Same goes for the EXUP Valve, wich im sure can be totally disabled(fixed wide open)and bypassed without spending a truck load of money.
Also done a lot on bikes like the Suzuki M109R.
If the bike “needs” a “programer” after doing this, well…u are stuck(fudged) and gotta fork those dolars over like it or not.
P.S: I have always liked your fly weight supermoto since it came out. EFI was what really caught my attention at a time the OLD DR-Z400 SM it’s still carburated. THE SHAME…SUZUKI.

My apologies to the other readers for the Tread HiJack.

the primary reason 4stroke made the innitial impact they did was the electric power delivery, whining from the track monkeys who swore the 4s was slower ( lap times by said genious were almost always faster on the “electric” 4s).
“it doesn’t feel as fast” whining prompted the oem’s to engineer the massive advantage of the innitial few years of everyones 450′s (electric freight train power delivery) out of the engine’s in favor of 2stroke hit and narrow power bands thus eliminating the advantages.
I’ll take my hammered 03 crf450 over any of the new offerings for blasting around the east idaho mountains, what most of the country calls “mountains” we call kiddy hills, that said nothing compares to the first few years of 450′s regardless of red or blue for tractoring around the mountains. ported piped 2s 500′s running on race fuel can’t climb with high hour (1500+) 03crf450r with an e series pipe, not a boast, simple fact…

Having dealt with sleds for years, the new “clean” 2s hotrods are just as expensive to maintain as a 4s, with substantialy lower service life.

For the tool thinking dirtbikes need to be massively differant to be worthy of the revised moniquer, 1st look up the deffinition of revised, 2nd as allready stated a dirtbike is a scalpel precision designed and refined over many decades to excell at it’s intented purpose, theres a reason they are shaped that way and look a certain way, it’s what works best…

There is a huge gap between a racing four stroke and a street legal fourstroke thanks to emissions. I have a wr250x, which is a great bike, however… There is a flapper to choke off the air inlet, and a valve to close off the exhaust pipe. Programmers are available at $400. Weight is 300 lbs (100 of which is the muffler).
It would take a ton of work to get a crf250r past emissions.

KTM is still playing the 2 stroke game and I haven’t seen a new 250SX at the track in years. Riders have voted with their purchases, apparently they are asking for 4 strokes.

There is alreay technology (its been around a while) that makes exhaust emissions 2 stokes cleaner than 4 strokes. Pressure from US regulatory committess pushed for 4 strokes and pushed out 2 strokes. The manufacturers were only too happy to go along with that, they made a lot of money of the new technology. Now they can reintroduce the 2 stokes and make some a bunch more money.

I still have my 02 CR250. It’s just fine for me. Better bike than I am rider…

It(2 smokes) should have never gone away. EFI and today’s powerful ECUs would have done wonders to clean them up enough to come down to 4strokes emissions levels (maybe even street legal)…ahhh, day dreaming is a bliss…lmfao.
