1971 Honda SL350 Dirt Bike Bobber Build


This is the story of how i turned a 1971 Honda SL350 into a dirty old dirt bike bobber

I never had any desire to build or ride a chopper or a street bike for that matter but ive been riding dirt bikes all my life... then one day i decided to build a dirtbike bobber


so heres what i started with...

heres some pics of the bike before i touched it... the bike wasn't mint so it was a good candidate to chop up

one of the reasons the Honda SL350 is a good bike to hardtail is because of the double downtube / cradle frame.. or so i thought

then i cut the back end of the frame off.

i welded a brace between the two downtubes and the rest of the frame before i cut anything so that i wouldn't loose the original shape

then i butt/plug welded some solid steel slugs into the ends of each downtube

next i built the battery tray and started to get an idea of how i wanted the tail section to look

i needed to make sure the geometry of the frame was good so the bike would ride straight. i also wanted to use the original rear wheel dropouts. i dont have a fancy frame jig so i made some swing arm extenders so i could float the dropouts out in space and build my hardtail frame around them. once the frame was built i planned to cut away the original awing arm

i made the swing arm extenders adjustable in length so i could play around with different frame stretches until i got something i liked

Nice!.

But most of the pictures are too big for me to see on my home computer.
