Honda recently had some fun with the moto media, inviting them out to ride a new bike...but without giving them any specifics as to what it was. They're probably still chuckling at the range of guesses...everything from Works bikes to electric military scooters. In the end, it proved to be something very worthwhile, their eagerly anticipated, and brand-spanking-new 2013 CRF450R. 

There had been some teasers of things to come from the GP side, and a couple variations of different bikes out there, but as you can see, there's a lot in the all-new here, including the aluminum frame and swingarm, as well as the lighter subframe and airbox. The suspension components are all-new, with the KYB PSF (Pneumatic Spring Fork), and new KYB rear shock. They also added some goodies like a new dual-muffler setup that's designed to be more compact, as well as meeting current sound levels. The look is new, too, with a more aggressive and minimal style to the bodywork.

Those are some of the big hits, but they didn't stop there. They added an improved footpeg mount with a new debris-shielding design, as well as new front and rear rotor covers, new Dunlop MX51FA front tire, and a .16/gallon boost in fuel capacity.

What's new in the powerplant? There's an all-new piston and a boost in the compression ratio, as well as a new two-hole oil jet adds extra cooling to the piston’s underside. The cylinder head has revised porting and 1mm larger exhaust valves. Add in revised cam timing, an all-new six-spring clutch design, updated transmission, and all-new radiators that are mounted lower in the chassis, and you've pretty well covered the new here, short of changes to the fuel injection and ignition maps.

How about a couple videos to help you digest all the changes here? There's one that covers the new features, and includes some post-ride comments from our tester for the day, Scott Champion; and another that deals specifically with the new KYB PSF fork.

    Needs black rims... When do you think we'll start to see more carbon fiber and composites in the frames? That could drop weight significantly... and, yes, it is durable. Probably be 15 grand for a new bike, though...

    i recall seeing a european production bike a couple years ago with a carbon fiber subframe/airbox and carbon fiber incorporated into the frame and swingarm (might have been a TM) msrp was 27K and change, and with exchange rates at what they are now, I would bet its well over 30 large. but when i case 100' jump, i'd feel much safer with aluminum under me.

    Regarding weight, do they always list their weights race ready or is this new?

    race ready probably means with fuel in the tank

    keep in mind the 2012 was nearly 10 pounds lighter than the rest of the 450s. Besides, its all about perceived weight. My concern is the forks. Air pressure changes with atmospheric conditions, as well as while riding. Won't air pressure rise from friction the longer you ride?

    i am 99% positive that because a fork is solid metal that is sealed off, outside atmospheric changes wouldn't affect the inside pressure of the fork. Temperature would definitely affect it though.

    Atmospheric pressure does. Bleed your forks then drive to the track. Especially if track elevation is higher. When you get there you will have more pressure built up

    I'll tell you why atmospheric pressure is not a concern. Because if guys like you know about it and how it changes with temperature and elevation, CERTAINLY the suspension ENGINEERS who invented and tested it know this basic principle of phsyics and I can assure you they have accounted for it. Now back to your desk jobs........

    No need for the hostility man. Everyone ive spoken to about these air forks has similar concerns. Obviously the engineers that designed them know far more about them than you or I ever could, but they should release something (i.e. a video) to address these common concerns from laymen. after all, its the people with desk jobs who are buying these bikes and keeping these engineers employed.

    guys, i gotta say that the bike looks awesome, but how in the hell can you say that the new desing saves few pounds in here, another pounds in there when the bikes curb weight is 4 pounds heavier than last year?? i don't buy anything about the new exhaust and frame set. im a honda lover, but if something has been forgotten over the las few year is the weight saving, which is very a important thing, i was really expecting a big change in that way with all the paraphernalia of the new bike.. (i ain't proud to sound like a critic guy and i've always looked up to the honda but this is to concern) still hope to see SOME change for the 250.. still the bike looks WAY MUCH BEAUTIFUL than the others!
