** Current Status **






Starting with a 1963 front loop and matching motor and spare 1968 motor this bike was primarily a parts bike I picked up to build another triumph bobber in the works. After throwing on other spare parts in the garage from other builds it started to take shape and thought It deserves a new breath of life.

Influenced by Angry Monkey motorcycles with some styling queues from The Salinas Boys.

In the beginning I had plans to make more of a traditional chop, frisco tank etc but I decided I loved low cholo chopped low riders better.



Decided to get a springer, but none of the DNA ish. I had a custom 6" under 17 inch from neck to lower axle fabbed to get that stance and lines just right.

Thanks for the feedback. I'll definitely put some head steadies back on. Also, hardtail is 2" stretch, 2" drop.

Killer looking build so far. It's the little things like headlight placement and angle that make something stand out from the crowd versus one that's just been bolted up however it fits.

I agree on the alloy cylinder bases catching hell in the absence of a set of head steadying brackets. There's ways to go about it without them interfering with your look/lines.

Also, the springer looks at home but am I the only one who actually maybe liked that short fork front with the disk better??? Either way, totally sick build so far. Should move along well too with those engine mods.
