Economy was booming during this time. You couldn't keep bikes on the showroom floor with the 4-stroke revolution.

Mazda dropped Yamaha a couple years earlier for 5/6 years without any outside sponsorship until San Manuel jumped in. That's when the economy took a dump and all the Factory teams were looking for money.

Hey that's my YZ! I did a rebuild on that bike awhile back. It was cool going through that bike and seeing some of the trick bits. That pic I took wasn't to show the clutch pack as much as the Ti that was throughout the engine. Anyone can buy Ti kits to save weight, but going inside the engine isn't done much by anyone other than factory guys. The Ti on this Metcalfe YZ125 was all YMC Japan. A lot of the plastic was held on with aluminum fasteners. They didn't run Ti Linkage bolts for reliability but most everything else was. I actually got some insights in talking to Metty's Mechanic from back then, Jared Coles. The way they prepare factory bikes is cool. Rebuilding the wheels, all the bearings were open (rubber seals removed), outer plastic dust seals snapped off the wheel spacers all to reduce drag. The Triple clamps had a thicker stem, smaller bearings and thicker races. I'm sure that was to fine tune rigidity. I sent the headset to Pivot Works, but they were unable to match it. Luckily it was all in good enough shape to reuse. The radiators are stockers that had been braced and welded for strength. ICW (www.icwradiators.com) does similar work. The frame had tabs welded in for skid plate and a vortex ignition was relocated between the radiators.



Here's a link to the thread I posted pics to:

MXA posted the test of the bike from 2005 here:

Man that's sick!!!! Good piece of history there mate!
Now the public have more access to technology and in sites to what factory parts are made etc..
Id love to get my hands on an early 2000' 2 stroke to see how factory i could get it, If not.. better then a factory bike with all the technology we have these days.

Jan de Groot built some amazing bikes! He wasn't afraid to try something new. RIP

Seems he wasn't happy with how the rear suspension of modern bikes work.

I was going to post that 2004 Jan de Groot Kawasaki. I still can't work out how it works. Such a shame he passed away.
There were claims a few years back that the under frame shock was going in to production.

If I could ride one bike from history, that'd likely be it!

What does an early 80's Honda factory bike weigh?

Does any one have photos of Chad Reeds KX he was racing in the GP's late 90's?
Rumour had it that was one of the most expensive 2 strokes at that time and filled with one off custom parts. Would love to see what goodies they had made for that bike.

I think some collector in Europe (Belgium? or Netherlands?) got his hands on it if I'm not mistaking.

Someone on here might know for sure.

Reminds me of the Answer Roost Boost, and I'm dating myself by knowing what one is. LOL

Man..I haven’t thought about that in forever. My dad had one on his RM125 when I was a kid and I never knew what it was for. I thought it looked cool tho laughing Hell, I still don’t know what it did or what it was for
