I knew the new bikes were getting heavier but that's almost sad

Wow, the RMZ 450 weighs 244 poundsThat,s great news
I can,t wait till they add traction control and a jake brake 
so the lazy 4-st. riders never have to touch there brakes or worry abought spinning the rear tire. Then the 450,s will weight 279,then it will be like old times passing 30 riders in the 1st lap .

YZ250 and YZ250F have same weight these days, yet YZ250 feels lighter..
Yep. All because the YZ has no valves.
The 2 stroke motor lowers the centre of gravity.
Still amazing they have got the F motor down to the same weight.

The YZ and YZF have the same frame.
I know 1 or 2 years ago the YZ came with a Ti spring while the F did not.
Not sure if that is still the case.

I wish you were right.. The YZF comes with a perimeter frame. The YZ comes with a alloy backbone frame, geometry hasn't changed in 10 years.
I suspect the 250f engine is still a little heavier, and they make it up with the 8-10 years in chassis development.

Jake brake - now that's funny!!Haha yeah dude,it could be the future 4-st clean burning diesel complete with a jake brake,on board air compreeser for your air brakes and air horn.
haha Imagine the victory speech, oh man I spun the belt on my compressor and had no air brakes,good thing my pc racing special tuned jake brake was working awesome,my pc racing traction control worked awesome-I never spun the rear tire the whole race,I got a little outa control on lap 20-cus I knew my factory airbag was packed and ready.I hope the fans enjoyed the race tonight,I wanted to put a great show on,I had my 6 litre honda sreaming-rpm max 2,800,jake braking getting huge air. I would like to thank pc honda diesel racing, anti gel, maxima injector cleaner, ebc air brake systems, brain wash beverage co., my 12 robot pit crew, my aero cab engineers,I think we have the best and most comfortable cab,we had a couple problems with the voice activated mirrors and tear off windshield,but we still got the W.
