10 worst dirtbikes of all time...

Nope Frosty, just the CZ and Rokon. As if that isn't enough..........

4. YAMAHA YZ490 (MOST YEARS). Yamaha introduced the YZ 490 in 1982, after a solid run with the YZ465. Sadly, the 490 was heavier than the 465, nowhere near as reliable, horribly difficult to start (hot or cold), came with a grim suspension, vibrated enough to bring blisters to your hands and was impossible to jet.

If you jetted it rich enough to keep this dog from seizing, it would blubber, puke, foul plugs and produce no power. If you jetted it to run strong, it would invariably seize. It came with air leaks, a wandering ignition, gimpy motor mounts and the worst case of Yamahop at high speeds since the original DT-1. Yamaha issued a mountain of service bulletins to try to fix the problems. None of them worked.

Gee that guy on the 490 at Ravenswood must know something the rest of the world doesn't........
I think most of the bad publicity about the 490 was started by Rick Siemen and the rest of the world has ran with it ever since. Which is probably good if you own one because there's about a zillion parts for them still available from Yamaha...

Which guy on the 490 at Ravo Rossco?

The first YZF400 takes my vote as the one of the worst bike ever.
This bike changed the life of many a rider> 
and the guy who was the supposed development rider was held up as a hero.

That's a bit harsh Noel.. I was stoked to be able to race a 4 stroke that could beat the 2 strokes.

The CR450 definately belongs on that list. I bought a brand new one thinking it was so cool and going to be the best thing i'd ever ridden and it turned out to be one of the worst.

It was Peter Clarke on the YZ490 at Ravenswood Brent.

Hmmm, don't know if I'd be so excited about having to ride something designed to beat something half its size!

Why not if it got results and was legal?

[Canam370]

You are right.....just as well they had changed the rules to allow them!
