I can't renmember which magazine I saw it in, but Honda has made a prototype TRX250Or they might call it the TRX250XX so they are not using the name of the old 250R. Anyways, this was a quad designed like the 450R. It has upgraded Showa shocks, liquid cooled and everything else like the 450R. They took a CRF250 motor and applied it. Here is the kicker, not only would they be the only company with a race worthy 250 they claim that they lost no power transfer. It puts out 28-32HP. That is the same as the CRF2250. If they can actually complete this, wow! The TRX450 puts out 32-35HP stock. That is impressive for a 250.

Honda needs to step it up in ALOT of catagories. There 4x4 sales have always stayed pretty consistant. The are really hurting in the sport class. They need to revamp the 450R. Rumor has it that in 2009 the CRF450 will have EFI. They expect the TRX450 to follow it's big brother into the EFI world but not until 2010.

I LOVE the idea....250's are great for people who want to ride but don't want a lot of power...but, it looks like if what Bot is saying, they'll have almost as much power as a 450....I wonder how my 400ex power falls into the mix...anyone happen to know off the top of their head? That's something I've never searched for.

Is this real world hp and not manufactures glory boy stats .

They seem pretty accurate, some them seem low to be from the manufacture. I know that the CR500 puts out 62HP. I can see a 500cc motor losing about 10HP in the transfer from a bike to a quad. That's what makes the TRX250 prototype amazing or hard to believe. They claim they loss little to no power in the transfer.

That is stock. I would like to know what my LT 250R is putting out not with the mods on it.

I would also like to know what was done to my friends Scrambler 400 to get it to almost 100 hp.

I know they bored it and I am sure changed the clutch but it is so scary fast. 34 to 90 something hp is

a big jump.

I'm wondering what my Tri-z will be putting out when i get it fixed. I found a place that is gonna do port and polish and mill the head. I would almost bet it was putting out at least low to mid 50's before and there's no telling what its gonna do when i start running better gas with a slightly bigger piston ports and head mill, its gonna be crazy. :shock: :shock: :shock: :shock2: :shock2: :shock2:

I have that magazine laying around somewhere.I thought it was a cool article;but it made me feel bad that a 250 could have as much or more power as my 400.I read somewhere that with a few simple mods the 450R will put out around 50 hp.I'm not sure of the truth in that though.I'd like to know the power to weight ratio of the KTM 525 quad and the Kawi Prairie 650.Something else I'd like to see in the future is a stock oem turbo UTV or ATV.I think forced induction is awesome

Yeah, it did a little bit. Back to the 250R, I just read that the main thing holding Honda back from releasing the 250 is cost. The 250 has generally been an entry level quad, kid friendly(against man. recommendation) and cheap in cost. They would have to sell this one around the cost of the 400ex. I think it would beat a 400ex.

Posted

bahaha, they seem about equal, from what I've read and heard everyone say on here....I know alot of the old 250r parts fit 400ex's....so would it be safe to say that the 400ex is just the 250r's younger sibling?

Posted

The 400ex is the baby sister of the old 250R. The one I'm speaking of is a 4 wheel version the CRF250. Not the entry level shaft driven machine they have now. This is a 30HP race machine. Adjustable shocks all around, liquid cooled. Pure sport!

did they release concept art?

..

400ex parts fitting 250r and vice versa...:confused:

sounds weird..

a 250 two stroke and a 400 four stroke seem like they would be WAYYY different..

Maybe like the grips and foot pegs!

They have an actual photo of it not just concept art. I can't find it online any where. It is the April 2008 issue of dirt wheels. From the profile picture, they either put dual exhaust stock on it. Or they went against all trhe other TRX models and put the exhaust on the left side.

That 250 in Dirtwheels was a prototype. Not slated for production anytime soon. It did look pretty cool. If the new Raptor250 sales take off, Honda is gonna want ramp up th R & D on that thing and get it on the market!

      Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.
