Updated with more pics!  Thanks again Bob!  And once again Nice Job!  I REALLY like these sorts of builds.  Very Creative.

Bob Decker sent in some pics and links to this really cool custom Briggs and Stratton powered custom but this is the only one I could get to that was big enought to use. I’ll update the post if Bob can get me some more. I love this concept. I’ve looked at the big Briggs engines and before and thought that they were plenty powerful enough for a motorcycle. 35 HP and 52 ft lb of torque ain’t bad!  Guess I was right! Thanks Bob!

I love the bike but my bedroom overlooks Lilac Alley and would love it more if you didn’t race up and down the alley late at night and let it idle in the alley.sorry to be a pain but my bike sets off car alarms as well but I try and do that on other peoples streets…

Dan Noyola sends in this wicked little custom build. Did some hunting and found his blog!  Go HERE  for his blog build pics!  Now don’t be shy about sending me links to yor blogs and slideshows fand such!  I love these kinds of builds. This once again proves that imagination and creativity are more important than money. What a cool bike.

Dan Writes:
It was put together in a couple of weeks for a few hundred dollars for the Dirtbag Challenge.
My ladyfriend still rides it regularly.

Dirtbag Challenge sounds like a blast. Thanks again!

Update Request: Can the owner please contact me. A moto Morini Flattracker.


Pete Giammalvo (or anyone who may know him)  if you’re reading this can you please contact me.  I received a request from someone to publish these pics of your bike and I’d like to put you in touch with him to work out any permissions.  Thanks!

Reader Pete Giammalvo sends in thise pics of what I believe to be a really cool Moto Morini flattracker. I’m also guessing that it’s a 3 1/2 (or 350) model.

Thanks Much Pete!

UPDATE: An Old Schoo Guzzi Adventure Conversion.


UPDATE: Craig in the comments sends a link to the original blog post.  The original post with lots more pictures is here: http://zecraignosmonstercycles.blogspot.com/2010/09/steve-mcguzzee.html. Looks to be a great blog too! Be sure to check him out! Thank You Craig!!

It’s written in french so his post through Google Translate and came up with the following from his blog post:

Transformations Guzzi scrambler are rare and successful ones are exceptional.The difficulty is the design of the chassis designed by the engineer to moult Tonti farm tractor perched high in a sleek racer and efficient on the road.The frame lowered, stiffened by a large tube bracing welded and fitted with a wheelbase folds difficult contortions that would impose the first motorfreaker come.This scrambler is truly remarkable. If I understood the comment by the Italian author who is an inveterate chatterbox, this embodiment is characterized in this way:
The idea is to evoke the CR 400 Husqvarna by Steve McQueen in “On Any Sunday”, it specifically (source Motorbike Search Engine):The original model is a 1000 SP1. The engine has been boosted by Dromo bike to make him spit up to 90 hp (!). The collectors have been sawn and re-welded to produce a high exhaust 2 into 1 on the right side of the machine.For the part cycle, the fork tubes have been lengthened by 10 cm, the bridge from a V7 hosts a bevel in the short report 6.32 equipping police motorcycles, folding footrests are provided by former Aermacchi. The wheels 18 “have been retained and the fenders T3. The main stand home-made” notes “instead of bridge.The reservoir is a special V7 in its small capacity. It is decorated with the autograph of Steve McQueen and logos side are drawn in the style Gilera. The saddle is a Cagiva 125 redesigned. The lighthouse mesh that contains the start switch is provided by a Guzzi TT 125. The instrumentation is reduced to a tachometer. The clignos are retrieved from a CB750 Four.
A personal appreciation, but I feel it remains to verify that the swing arm is shortened to reduce the wheelbase, which contributes greatly to the harmony of the whole terrain in this version.So far, the prettiest guzzi proto scrambler I’ve ever seen … Che bella!

How cool is that!  Anyone have more info on this beauty?  I’d love to know more.
