Mad Bros #02 : The splitlane

Mad Bike #02 : The Splitlane

This is my 1993 Yamaha SR500 That I rebuilt from the frame up.
In house made the seat, the upholstery, the bars; painted the metalflake tank a while aho and added the flames later. The rest is the usual stuff : blinkers, headlight (from † http://www.eightysixchannel.blogspot.ca/)  vintage looking rearlight. Longer control cables.
No battery, KN filter … blablabla
Upswept muffler and Hagon shocks.
Kick pedal is home made.
Gonna be racing it at Dirtquake this summer, so I have to change it to “dirt track” mode.

Extras :


I met Max through a common friend.
He mentioned he had a Honda bobber project in his room that was on hold. We agreed he would bring his roller to my “garage” so we could work on it together.
Honestly, I never thought it would take this long, because this was in April. Anyway, I can say that I am pretty satisfied with the overall look of the bike. See I’ve been into bikes for a little while, but my discovery of California Choppers is more recent, and has caused a severe addiction. Here in Europe, it seems like choices reduce to cafe racer or street tracker. I dig it but bikes end up looking the same, and same aftermarket parts are used. My belief is that choppers allow even more personality expression or extension.
The mix of chrome and rust. That’s what it is.

The wiki definition of chopper is :
A chopper is a type of motorcycle that was either modified from an original motorcycle design (“chopped”) or built from scratch to have a unique hand-crafted appearance.

So that means it s a process rather than an style; I thought we could go in that direction even though we didn’t have a panhed or a shovelhead in our hands.
I had loads of fun rebuilding this bike, and Max was the most patient and tolerant guy with me; so thank you man.

J’ai rencontré Max par l’intermédiaire d’un ami commun.
Il a parlé d’un projet bobber Honda dans sa chambre qui était en attente.
Nous avons convenu qu’il apporte son engin dans mon “garage”.
Honnêtement, je n’ai jamais pensé que ce serait aussi long, parce que c’était en Avril. Quoi qu’il en soit, je peux dire que je suis assez satisfait de l’aspect global de la moto. Cela fait un petit moment que j’aime les bécanes, mais ma découverte des Choppers Californiens est plus récente, et cause une dépendance sévère. Ici, en Europe, il semble que les choix se limitent au café racer ou street tracker. L’inconvénient c’est que les motos finissent par se ressembler, parce que les mêmes pièces aftermarket sont utilisées. Ma conviction est que les choppers donnent une plus grande liberté d’expression.
Le chrome et la rouille.

La définition du wiki est:
Un chopper est un type de moto qui a été soit modifiées d’une conception originale de moto («hachés») ou construit à partir de zéro pour avoir un unique aspect artisanal.

Pour moi plus qu’un style, c’est un processus, alors j’ai pensé que nous pourrions aller dans cette direction, même sans avoir un panhed ou un shovelhead entre les mains.
J’ai eu beaucoup de plaisir à reconstruire cette moto, et Max a été très patient et tolérant avec moi, donc merci tête de mule.
