Asumati Street Tracker

Writing about custom bikes of fellow builders teaches me a lot of things that have apparently nothing to do with motorcycles. So, I wondered, like you are, what is the story behind the name of this new creation? It was built by Jim Giuffra at AFT Customs (and of course his crew of girls) for the Jackson Rancheria Casino Hotel. And this establishment wanted the bike to be a tribute to the Native Americans Miwok tribe (also spelled Mi-wuk) from Northern California. And I learned that there is a tale of young brave of the tribe who fought a long and furious struggle with a grizzly bear, finally killing the huge animal with a tree limb. His accomplishment was so remarkable that his tribe called him Chief Yo Semitee (for a full grown grizzly) and this name was passed to his children and eventually to the entire tribe and even the valley they lived in. Like most Native Americans, the Miwuks had no written language until they came into contact with white men. And when they tried to write down the Indians spoke, they gave to the word Yo Semitee different spelling – usuimati, uzumati, oo-soo-ma-te, and the more familiar yosemite, but the Jackson Rancheria Band of Miwuk Indians prefers to use Asumati…

Your questions about the name Asumeti being answered… Jim Giuffra, the most well known builder for crossing over from metric to v-twin creations and back to metric custom bikes, explained to me that he wanted this Honda VT750ST creation to look and behave like a Street Tracker, meaning keeping emphasis on very good handling. As usual the crew of AFT girls did a lot of the build, Jim stating a percentage around 70% of total labor time. For example, Nalani – only 18 years old – pounded out the side covers, sub fender & removable tail section. As a side story, to reward all his AFT girls who have worked on this project he send them all in February to builders Cole Foster & Greg Westbury where they will follow a class in metal shaping.

It is important to mention that Asumati is a fully street legal motorcycle (horn included!) weighting only 420 pounds wet. The bike is a convertible with a removable tail section if you want to have a passenger or ride solo. A Paugho tank was cut, widened, tunneled & reshaped. If you are looking for the radiator, yes it’s now relocated under the seat. Motor is a naked engine design that AFT Customs pioneered with a VT750 performance kit, top end narrowed 2 inch. high compression pistons & cams and custom exhaust. The Race tech shocks were custom made specifically for this bike. The Yamaha R1 front end uses a custom set of trees & risers sourced from Alan Kraus of Kraus Motor Co. Braking via Beringer hand controls and calipers. Moto gadget instruments. Grip Ace digital switches inside grips & turn signals. License plat rotates from vertical to horizontal. Bars are 1 3/8″ by Easton. Leather by Duane Ballard. Paint by Todd Evans.

    I like pretty girls. The motorcycle is neat too.

  2. 2 Sportster Mike Jan 23rd, 2012 at 8:49 am

    What bike?? Somehow I can’t see one…

  3. 3 MCRIDER Jan 23rd, 2012 at 8:54 am

    All that work on a metric motorcycle! Too bad. It will never receive recognition and will never be worth anything.

  4. 4 Biker Jan 23rd, 2012 at 10:02 am

    Nice work on the scoot! Enjoyed the story on the name. Half naked women standing around a sled….you cant go wrong with that!

  5. 5 ray c wheeler Jan 23rd, 2012 at 12:21 pm

    Another stellar build by Jim and his Crew! See you in Cincy?

  6. 6 Dinky Dot Jan 23rd, 2012 at 12:22 pm

    All its needs is a rear fender It will be great, when its finnished, Oh yeah maybe a nice set of pipes to change out that cobbled together crap his 3rd grade son must have done when he wasnt looking

    Metric or domestic, it doesn’t matter, this bike is a true custom motorcycle that represent Jim’s dynamic creativity while watching over the female builders/models who are the ones who actually do the Fabricating and wrenching on this custom motorcycle. i appreciate something different and so does the up and coming generations.Nice custom bike Jim.

  8. 8 AFT Customs Jan 23rd, 2012 at 12:47 pm

    There is a small inner rear fender bolted to the swing arm & as the artical states there is a removable rear fender / seat. Dinky – thanks for your educated kind remarks on the pipe. That’s a perfect name for someone who does’t feel that they measure up & has to tear down others work to make themselves feel important.

    This is also the story of how Yosemite National park got it’s name.

  10. 10 Philippe DANH Jan 23rd, 2012 at 1:18 pm

    Another nice build by Jim and the girls with a great story to boot.

    Jim has chosen the Metric route which is more difficult in my views with near zero aftermarket to just bolt on. He has to create everything and that makes it harder and those engines are not as sculptural as a domestic V-Twin and it’s much harder to make them stand out. So congrats to AFT Customs.

    For all of the shit talkers.
    Chances are you don’t ride anything and you might have a friends motorcycle photo in your back pocket.
    Show us what you’ve built this life time?
    Should be interesting.

  12. 12 Ernie L Jan 23rd, 2012 at 1:41 pm

    That is the best looking chopped metric bike I have ever seen…I own and ride HDs but I’d ride that in a heart beat..

    There is not that I am aware of a lot of after market performance parts for the Metric v-twins. The stock 750 metric v-twins are pretty anemic.

  13. 13 jack flack Jan 23rd, 2012 at 2:50 pm

    Any bike without a rear fender seems dangerous. I can’t help but think what would happen if you hit an unexpected pothole or got rear-ended. That back yire would try to force your ass between the tire and the frame.

  14. 14 fuji Jan 23rd, 2012 at 3:12 pm

    Great looking bike but streeet tracker , its not. Way off

  15. 15 TPJ Customs Jan 23rd, 2012 at 4:23 pm

    Great job Jim. I won’t even comment on the idiots cause they have way more time to computer bash then live in the real world and create something. Great job keep up the good work whatever power plant you chose to use.

  16. 16 stopsalot Jan 23rd, 2012 at 7:44 pm

    Dinky… would love to see what you build and or ride. Props to Jim for going the metric route, like it has been said the HD world is full of products ready to bolt on. Jim consistently builds bikes that win awards and get noticed by people with an appreciation for the moving metal art medium. Hot rods were born out of necessity, take what you have and improve upon it. Great work to Jim and his minions (tripe threat: smart, talented, & beautiful) ……….

  17. 17 jack flack Jan 23rd, 2012 at 8:34 pm

    To clarify: the bike looks great but if it is not safe to ride I don’t care how good it looks. I don’t like bikes with no front brakes either, they might look good but but i can’t overlook the obvious.

  18. 18 Steve Iacona Jan 23rd, 2012 at 8:41 pm

    Jim and his very talented crew do outstanding work. Flawless and well thought designs are the only way to describe their work . It’s was great meeting them

  19. 19 Seymour Jan 23rd, 2012 at 10:11 pm

    Oh brother, a honda and some xxxxx. Y’all a bunch of sellouts.

  20. 20 Little Bear Jan 23rd, 2012 at 10:36 pm

    @jack flack, It has a front brake! And with a nifty looking rotor too.

  21. 21 Nobody Jan 23rd, 2012 at 10:47 pm

    Nice scoot. I especially dig the engraving.

    Using the power plant from an Indian would have been a fitting thematic touch.

  22. 22 RUB Jan 24th, 2012 at 12:35 am

    so much time & money on something that will always be a red headed step child , with a wanna be riding it , explaining to everyone how cool it is . workmanship is outstanding , but it is what it is .

  23. 23 Sheridan Jan 24th, 2012 at 3:24 am

    I’m impressed by the engineering involved in hiding the radiator, that would not have been easy. Wonder how well it cools now though? Best looking Honda VT750 I’ve seen. Honda could have taken a leaf out of this book before they came out with the Fury.

  24. 24 Maddpuppy Jan 24th, 2012 at 6:22 am

    Great work AFT, I drive past your shop quite often, i wish you would open the roll up door so i can see the crew ! then Id probably stop in.

  25. 25 mid-north-kustomz Jan 24th, 2012 at 7:19 am

    ray c wheeler,,, yr a funny c–t ! agree with u 100%. but lets give credit 2 all the assemblers out there ahhh haaaa ha haaa. !

  26. 26 hk Jan 24th, 2012 at 10:46 am

    whats wrong with a metric ? Is there something wrong with actually reliable engineered engines ?

  27. 27 AFT Customs Jan 24th, 2012 at 12:56 pm

    SEYMOUR – You positioned yourself at the top of the scum pile on this site for calling those girls whores. You sound like a coward that beats women . This site won’t let me say what I really think of you.

    Jack Flack – the artical states that there is a removable seat/tail section so the bike can be ridden either way. Cyril didn’t print a picture of it. You won’t slide off the seat if your holding on to the handle bars.

    Sheridan – The radiator works excellant under the seat. Has plenty of air flow, fan, thermostat, and holds more fluid than stock because of extra length of hoses. We’ve been doing this for 7 years now with no problems.

  28. 28 burnout Jan 24th, 2012 at 1:09 pm

    Well done! peace

  29. 29 chaos cycle Jan 24th, 2012 at 2:26 pm

    ive ssen this bike in person and gotta say the details you dont see in these pics are what make this bike so cool. as far as the girls, they are not just some gimmick. I talked with both Jim and shelby for an hour at the amd and shelby was very knowledgable and explained that Jim spends lots of time teaching them the way to do things but they actualy do the work

  30. 30 John Green Jan 24th, 2012 at 4:57 pm

    Jim has been showing bikes at our Sacramento show for many years and every year he comes up with top of the line original builds. Guys like Jim are what keep the imigination current in this industry. Great Build-Great Bike-Great Shop and a Gentleman to boot. Stay on track Jim you are in a good groove.

    @ little bear, of course it has a front brake, and I love the rotor. I was just stating something else I don’t like on custom bikes. @ ATF Customs , congrats at building one of the absolute best looking Honda V-Twins ever! People like you are the lifeblood of our industry. The cookie cutter Harley shops which are all alike and all carry the same stuff are very boring (yea I ride a Harley). Modifing or customizing bikes are what make bike shops interesting and differant. When traveling I always try to look up and visit local bike shops.Don’t take my comments as me being a hater, but I’ve seen a bike ridden in the rain with a small rear fender and I’m glad it was’nt me. Keep up the good work ATF!

  32. 32 barney Jan 25th, 2012 at 12:42 am

    Beautiful bike! Radiators do not belong on bikes ‘full stop’…excellent job on tucking it away. To the ‘nay sayers’ -get a ucking job!

  33. 33 Septic the Sceptic Jan 25th, 2012 at 2:03 am

    No mention of the engraver?????????????????????????????????????????

  34. 34 Aaron Glenn Jan 25th, 2012 at 9:44 pm

    Nice job! I really like this bike……way to blend the elements!

  35. 35 Chopper kulture Feb 1st, 2012 at 3:06 am

    Great job again you r are the man! You must love the haters because every time they write something negative they are basically telling you they ain’t worth shit! Again bro! You guys done a marvelous job!!!
