It's Here...the 2010 YZ450F

Recommended Posts

As crazy as that may sound, I remember way back when Honda came out with the RFVC engines for the XR350/500/600 there was a little cavity on the head or cylinder of one of those bikes that had a little cover that bolted onto it. Not sure what it was for, but I remember the magazines joking that it would be a good place to wrap a small potato in foil for an after-ride baked potato snack. Butter and chives could be kept in the tool pouch.

Good grief! Someone as old as me that remembers that silly comment! :busted:

That was Dirt Bike, back when it was a decent mag and not written on a comic book level with everything being described like it's related to eating (perhaps they're spending too much time watching the Food Network instead of doing bike related stuff? :banana: )

:thumbsup:

Honda has the engine tilted back, these things turn on a dime....Are the YZ's gonna make you all that much faster? Looks like Yamaha refined the concept, but did they invent the idea of titling the engine rearward? Didn't Honda just do that?

The Honda guys are really having a rough time with this, aren't they?

Honda didn't invent the concept either. All they did was to take a complete existing engine package with a vertical cylinder and rotate it in the frame, and not nearly to the extent that Yamaha did. As I recall, a couple of years ago, they rotated it forward and down. The fact is that the Japanese in general have invented very little, and refined a lot.

I didn't see anywhere that Yamaha claimed to invent the idea of a tilted back cylinder, pent roof combustion chamber, or anything else. But, I think they have done a good job taking a lot of great ideas and putting them in one package. Hopefully it all works as good as it sounds.

Same for the Germans

Im Gegenteil

Germans invented the 4-stroke engine, the two-stroke engine, the Diesel engine, the rotary engine, two or three different types of jet engines, including pulse and turbine, fuel injection, both mechanical and electronic, the sleeve valve four-stroke engine, the rotary valve two-stroke engine, a system of operating a four-stroke engine's valve train using solenoids instead of a camshaft, direct injection four and two-stroke engines, closed loop engine control systems, and virtually every other major conceptual improvement to internal combustion made during the last century, and most of that during the first half of it.

Americans did invent the steam engine and the bi-metallic combustion chamber though.

Now, back on topic.

So they were pretty good until about 60 years ago...:busted:

Im sure u would like to think that, but the answer is no, that thing is ugly! I think its a race between kawi and yami who can build the longest silencer, oh and nice seat warmer! LOL

The honda guys love to pick on the silencer.:thumbsup:

They always want the end of the bike they will see on the track looking good.:busted:

I haven't read the 34 pages of information on this bike so sorry if this is a repost, but will this bike kickstart forward since the motor has been reversed? I mean I know it would only take 1 gear to reverse it so that it still kickstarts backwards, but I was just wondering if yamaha did that or if it will kickstart forward?

The engine is not reversed, only the way the head sits on it. If the direction the head faced made any difference, a V-8 would be....confused. :busted:
