BIKES: 605 Supermotos from Around the Interweb

The internet, apparently it is not just for cats. In my usual google perusal of any combination of "ATK, Rotax, Supermoto, 605 etc..." I've come across a few pretty distinct SM customs, some better than others. I hope I don't come off as snide, because I think it is awesome what each of these people has done to make their vision become a reality.

#1 I'll call this one "OLD YELLER"

Yellow Frame and plastics? It almost looks factory! Wave rotor hotness. Black Tank. Black swingarm. Are those fork tubes anodized? And note the Non-ATK rear fender!

Swingarm seems to indicate 600 like the DT models... hmmmmm...

The 17's and especially these footpegs probably make this a whole lot more fun to ride.

#2 Yet another terrible alien supermoto headlight with a red white and blue motiff on this next one I'll call "ILL EAGLE ALIEN"

RED seat WHITE Tank BLUE Frame.

Terrible headlight is almost visible in this one.

The lack of number plates looks okay from the left, but that battery box begs to be hidden by some square footage of plastic.

#3 Sometimes dipping goes a little too far. This one I'll call "Midas Touch"

The black rotax looks pretty sharp, I'm just hoping they used something relatively high temp resistant on that motor and Supertrapp. Can't tell if that's a sprocket protector or not from the pics. The 320 mm rotor in front for stoppie time. It kind of reminds me of this one

#4 Fully stock looking except for the tiny wheel and custom fender, so I'll call this one "LITTLE FOOT"

This little 350 is a sleeper though because the owner did some engine work described later. Looks like they left the 18" in back. No additional views were available on his photobucket account, and no information about the fender on ADVrider where this was originally posted. The owner indicated on the forum that this was a 350 that he bored out to a 440. you might wonder why not 494 or 605. Well, a it turns out if you do the calculations, the limited stroke of the 348 (70.4 mm as compared to 79.4mm for the 494 and 81mm for the 605) means that even bored to 89 mm (494 bore)the total volume of the compression chamber will only be 440 cc. Even if he sleeved it out to 96.5 mm (bore of the 605), he would have only ended up with a 517 cc. That's enough math for now.

#5 I'll let you guess what the most prominent feature on this one is, meanwhile I'll call it "Hot Wheels"

Looks pretty standard except for the Yamaha tri spoke cast wheels.

Which is a pretty big accomplishment given that the ATK Talon size is seen as a "unicorn" fitment and so many people fret about destroying their dirt wheels to make a supermoto set. I wish there was more information available on how these bad boys were jimmied into position (Link up above to the description). It's not that I want tri spokes on the 490, but it might help the many of us interestd in not tearing apart the dirt set, and might give more options for rear braking given the "unobtanium" status of the rear brake rotor.

#6 Supermoto style with minimal investment! I'll call this one "18 WITH A BULLET"

I've often wondered why I shouldn't just relace the front hub to an 18" hoop to drop the bike a little and get a supermoto look. This guy did more than just wonder.

It might look better with a smaller front fender but overall the look is acheived.

The big drawback to this approach is the limited amount of tires available in 18" format. You might get the supermoto look, but you will likely end up mounting a rear tire on the front. This is somewhat contrary to the idea of making your bike into a SM, because the high sidewalls and lack of taper to the contact surface means no significant gains in cornering performance.

Well, that's it for this installment, I'll be keeping my eye on CL and eBay for other sweet custom rides. If you have any pics of some SM ATK's post them in the comments. NOTE: I omitted Bones and Michaelangelo's SMs because I have already posted them in previous blog entries.
