Title: 84 ATK560
Post by: bishboy on March 11, 2014, 12:03:29 pm
Just the thing to win that holeshot  ;D 

I believe the 84 ATK560 was factory fitted with drum brakes front and rear, but you would have to put an evo compliant front end on it

The same guy also has a 85 model for sale and a 83 CR250 with mugen bits and an ohlins USD front end :o

The '84 ATK had a countershaft mounted disc brake I believe. It'll never fit into Evo, or shouldn't be.....(said Firko, dreading that he's started another Evo flame job ::))

So the single shock is judged link-less like a YZ?  So if it had a drum rear brake it could be EVO. Odd bike that dosent really fit EVO IMO.

There is on drum brake to my knowledge Mick, it had the rear disc brake mounted on the countershaft and after that idea proved to be prone to failure, a conventional rear disc went onto later models. I may be wrong but I don't think there were ever any drum/drum ATK's. The single shock setup is very similar to the KTM system and isn't linkaged.

Firko, there was a late '83 560 version that had what looked like Yamaha front end with drum rear brakes, so this could be legit Evo with correct  front end, still a cracker of a pre '85 weapon for $2500

I've read that in fact the KTM is like the ATK, as Leitner did a linkage-less bike for KTM several years prior to their version.

cheers,
Michael

According to AmericanDirtBike.com, this is a photo of a 1984 ATK: http://www.americandirtbike.com/86-560.gif
It is clearly an Evo bike in stock form.
Note the KTM TLS rear drum, just like the one for sale.

I can't pick the forks/hub on the bike in the official photo, but they could well be CR480 bits.
I do recall Horst Leitner being quoted in MXA or US DB in the very late 80s or early 90s saying that he thought the best forks ever were Kayaba's 43mm forks from the early 1980s because they had the least stiction (and that everything else could be fixed).

It would then seem likely that the '84 ATK had '83/84 Yamaha or '84 Suzuki forks & front brake on it. Triple clamps look like Yamaha to me.

As to Evo eligibility with the CR480 bits... The standard ATK is unquestionably Evo legal. This ATK has bits from its era (actually older), so they're neither "later bits", nor is it "modifying the bike to comply".

I think only the 2T models had the countershaft disc  :-\

Nath....It's been stated that Evo has no era or period....so older / newer is totally irrelevant ( not my ruling, judgement, opinion......just saying )

Anyway, it looks like I'm picking up a moto sickle from you at Canberra round. ( fu...in uteless qlder's ) ;D ;D ;D

If the forks are from a non Evo bike (CR480 monoshock) then not legal as far as I was aware.

AMP Link. Isolates the rear suspension from the effect of chain tension. Apparently you wither loved it or hated it, with the better riders more likely to hate it.
The idea is the same as the ill-fated BMW 450/Husky 449/511 where the front sprocket is in line with the swingarm pivot - I've ridden a 449 and there was lots of weirdness, but I can't say that I thought the lack of chain torque on the rear suspension was noticable.

I love everything about the ATK's, except the tank.  I guess the Rotax motor is so tall that the tank has to be that high to have enough fuel capacity???
