WOW, cool!

I had no idea Maico was back! Way cool. Thanks for the link.

Now, having had 400 and a 450 Maico's in the past, I can't even imagine a 700! Holy moly.

But I'd sure like to give one a try!

Good luck and have fun, Mark H.

Ana rticle on the bike from 2003... (it's been around a while)

So You Say You Want Some Serious Horsepower?

Frank White put the ATK through the paces for a few laps at the Desert Vipers Grand Prix. ATK, the American-based company, has been around for a long time now. And for much of that time, they used Rotax engines of one sort or another in their own unique frames. However, the Rotax two-stroke technology has become rather dated, so ATK went hunting for some new powerplants. And while they were at it, they also came up with entirely new chassis designs. Interesting, for sure. Their approach is one that we like: all the bikes will be considered multi-purposes off-road machines, not pure motocross or pure enduro bikes. This means, simply, that all the bikes will come with lighting capabilities. They won't come with headlights/taillights, but if you need to have lighting for some reason, all you'll have to do it bolt on the lights and hook 'em up. Now, for the big news. Here's the new line-up for ATK: 250 320 390 500 620 700 THE 700cc ATK INTIMIDATOR! New King of the Beasts? The 700cc ATK is certainly in the running for that title. Naturally, our attention was drawn to the 700. Based on the latest technology from the folks who built the famed Maico/M-Star motors, the Intimidator (good name!) has a piston big enough to use to mix paint in. I was scheduled to test ride the Intimidator at the Desert Vipers Grand Prix, but my motorhome lost the rear wheels on the way to the event, and I spent most of the weekend getting the thing fixed and back home. However, Mike Hobbs from ORC, was there and managed to get some photos and feedback on the bike. Frank White (CEO from ATK) put in a few laps on the beast to shake it down a bit, so we can at least give you a preview. We'll arrange a full test session with ATK later on and give you some actual riding impressions. For now, here are some specs and info on the 700: Intimidator Specifications Engine Type: Liquid-Cooled, 2-stroke, single Displacement: 685CC Bore & Stroke 100X87 mm Carburetion: 39mm Kehin Ignition SEM lighting output 130 watt Starting System: Kick start Transmission: 5-Speed, Wide Ratio Fuel Capacity: 2.5 Gallon / 3.5 Gallon Front Suspension: Paioli USD Rear Suspension: WP Front Tire: Dunlop 755 80/100-21 Rear Tire: Dunlop 756 120/100-21 Final Drive: D.I.D. V6 520 O-ring chain Dry Weight: 238 lbs Plated pipe and left side kickstarter. Looks like a Maico, and why not? Carb is a smallish 39.5mm Keihin; pipe curls neatly up and out of the way. GPR steering stabilizer ? stock! Frank is justifiably proud of the latest ATK creations. Standard Features Talon billet aluminum hubs Answer Protaper bars Braided stainless steel lines Nickel plated exhaust pipe Radialite rear sprocket Excell rims GPR steering stabilizer Wave rotor disc brakes Talon rear hub; Radialite sprocket. Stock. Another Talon hub up front. Wave rotor and Brembo brakes. With the head off, a rather huge hole is evident! Options Tire choice Excell rim color choice Front wheel size (20" or 21") Plastic colors Seat foam and cover Suspension valving and springs Handlebar bend Final gearing Jetting Lighting kit Skid plate Handguards 3.5 gallon fuel tank Compact motor is based on the latest Maico stuff. White at work on the 700 at Adelanto. ATK is going to let the potential customer, custom order their motorcycle with the options noted above to fit their individual riding desires and conditions. This is new to this industry. The retail price has not yet been determined, but after talking with ATK folks, it will almost certainly be in the ballpark of between $6000 and $7000. When you consider the astonishing amount of top dollar items that come on the bike as standard equipment, you start to wonder how they can do that. Go price items like Talon rims, Protaper bars and a quality steering stabilizer, and you'll see what we mean. Performance? Since we have yet to sling a let over the bike, we'll give you the thoughts of Frank White, the ATK CEO who rode the bike at Adelanto: ?It pulls right off idle and all the way to peak revs with more power than anyone will ever need. It's sort of like a 490 Maico on steroids. The power is simply amazing and very electric!" With this sort of statement lodged in our mind, we're looking forward to a serious ride on this beast, and others in the 2004 stable of ATK bikes. Stay tuned to Off-road.com.

ATK = sells in US

Maico = sells in Europe

(both marques have a certain "allegence" in their respective homeland niché marketplace).

Don't know if available in Oz?

Scene: The Cromer Park reserve (up behind DEE WHY Sydney) one saturday afternoon... the early 90's. A police patrol car has a bunch of young lads on unregistered 80cc dirtbikes bailed up, for riding in the park...

Police officer: "Now you know you can't ride here fella's... Where can I find your parents, I wan't to talk to them..."

MX kid: "Look behind you bacon breath... he's the one on the 700cc minibike..."

Yep that would be it. I knew there was a 7 somewhere

I had a riding mate that raced a 1990 540 DXC that was prepped for Baja events. It was geared to pull 116 mph (190 km/h near enough) on fireroads/packed sand. It'd probably go faster on tarmac (hence the 125 mph figure that DirtBike referred to maybe?), but at that speed for prolonged periods on asphalt there were other problems to worry about (see below).

I pre-run and rode the thing down around San Felipe and other places in Baja with him on a number of occassions. The accelleration was like nothing else (SE like in some terms, but as it was far lighter and it hit WAAAY harder that the 950 twin... it was much scarier!). Punting this missile around in the open deserts of the Mojave, in Nevada, Arizona or even Baja... I can understand... but to ride it anywhere else (MX track, enduro singletrack), I thought was insane! But he seemed to enjoy it.

In my mind, you could only use a fraction of that power in MOST situations... it only came into it's own on the wide open whooped sections of the SCORE desert race courses... I can only imagine how brutal the ATK/Maico would be with another 160cc on tap!

Oh...? What was the problem with running the KTM 540DXC wide open on the tarmac in the 35 degree plus desert heat for a prolongued period???

The rear tyre would get so hot, that it threw the center knobs off the dunlop rear tyre... one time during a 10 mile blast down an extremely hard pack dirt road south of san Felipé during a pre-run weekend, it tossed one knob straight thru the inner rear guard, through the airbox and into the air filter element. Motor lunched it, locked up the rear wheel in a heartbeat and left a skid mark for near a hundred meters...

He didn't ditch it, but as he was standing up at the time, the decelleration threw him forward - his thighs hit the bars - and he was looking at his front fender, with the rear wheel locked, still doing about 85 mph!

When the chase van arrived the bike needed the barrel, piston, carb, airbox and rear tyre changed. RN just needed a change of riding pants...

Imagine the vibration!! God a >700cc two stroke, you'd be lucky to hold on to it for the vibes. It must have a >100mm bore, therefore a huge slug. Think about it, if it were a 4 cyclinder it would be a 2.8lt. Don't see many 2.8lt 4 pots in performance applications. Too much capacity per cylinder, heavy pistons, vibrations, poor cylinder filling etc. Of the few engines with cylinder capacities this large they need a balance shaft to stop vibes. Apparently the ideal size cylinder (for volume to surface area ratio) and therefore cylinder filling is 300cc as evidenced by F1 3500cc V12, 3000cc V10 and 2400cc V8. Also at that size it will be slow revving and need a heavy flywheel so it doesn't stall - making it hard to turn. There has to be a reason why smaller and smaller bikes are getting more popular for offroad use. A big bore is now a 300cc according to the other sane motorcycle makes.

Yeahbutt... 82hp / 101 kg who cares about all that stuff!

Auto... you could probably talk Nevbottomlesspockets/large garage/tolerant wife into getting one, so you and the lads can head out to NW vic and play in the sand...

Take Knackers, Mudguts and Camo along to document it all...
