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.
