Come on now these factory Goldstars were makin 40hp

@@JackF99 true!

@@JackF99 40hp? Yeah dream on buddy.

@@swemx7403 Stone stock DBD34 was rated at 39-42hp

@@JackF99 If thats so, It has to be on the crank. Then you multiply that with 0,85 and you get around 33rwhp. And before you wanna play smartass and comment on this.. I work with dynos all day long.

Early 70's friends had a Rickman/Zundap 125cc. A beautiful machine. Xtream light weight. Magnificent craftsmanship.

don’t have that counters anymore you don’t have a meet on the Monday all done online digital lap counter

Your bang on there Brian.

I couldn’t agree more …….something Missing from the sport ever since. Fans used to like the high speed bar banging action…..the supercorss stuff really is boring to watch after a few minutes and is one of the reasons of its decline imho

If the old pros like Bickers could get to ride a current senior motocross bike they would slaughter you!

Imagine their eyes looking at a 2021 ktm 450 SX f

@@toptiertyson1456 There's a YT video floating around from a guy wearing a helmet cam on a electric dirt bike in a race amongst 450's. Granted it seemed he was a better rider but was done and back at his truck before the rest crossed the finish.

Incredible! If you don't mind, can you describe it?

@@treskilion-9690 One thing you dont get in that film is the steep ness of some of those hills and the length of the track and the fact those big old goldies an the like were flat out along that Half mile straight also those hills were covered in large flints ready to have you off in an instant what i would say to any one who would like to see that area today is head to the top Butser hill the highest hill in Hampshire then drive down or walk down harvesting lane taking in the view over the wonderderful downland to the left and realising how lucky the riders were in those days to have the chance to ride across this magnificent landscape .

2021

Greeves with leading-link suspension up-front.....!!

Larry Huffman is the GOAT of announcers. Miss his voice calling races. I still watch Winners Take All all the time on DVD.

................. except that this is called 'scrambling' the 1950s and 60s forerunner to motocross

A fair amount of those WERE 2 stokes..Bickers and Stonebridge and the winner were all on Greeves..

I saw mostly Greeves with a few other 2ts thrown in. Did hear a four stroke in the fray, could've been maybe a cub or two? Too early for the BSA C15 or Matchless G2s.

Mr. Nunna- same producers made the old Godzilla movies, the people speak and 2 sec later you hear it. Ha.

I have 3 CZ bikes ! One was sitting for almost 15 years and started first kick after minimal maitenance and gas draining. Amazing bikes !!

@@worldsnextsupercar4362 I had a '73 250, I believe. Weird thing is, I don't recall where it came from. Raced it at Carlsbad once, then ended up with new '77 RM250. I remember watching CZ supported riders practicing starts at Rawhide Raceway without using the clutch. My Montesa VR would have spit the gearbox on the ground. Wonder if Bert's is still around in LA Puenta, he used to spend time at the factory, then bring a bunch back. Miss the old days.

You sound young by that statement but man has motocross come along way !!

Nope, Bickers had Greeves in the rear view mirror, was on CZs in the '60s. I saw many iron cylinders on those bikes, signs of older units than those that were produced later on.

I cannot believe my eyes, riders working on the bikes?????????

Would like to see todays riders wallo around in their pink leathers on these off cambers.

​@@davemenzimer5721 Umm.. there are off cambers on mx tracks today bud. The bikes of today just make ruts that would swallow these bikes.
