This bike started out as a frame and the boss wanted me to build a bike with the David Bird Street Tracker rear section for swing-arm bikes (which unfortunately is no longer available.) I kind of dragged my feet on it and took several years to build. I must have built at least 4-5 other bikes as this one got pieced together slowly using up any spare parts I had laying around the garage. The engine came from a swap meet and was supposedly rebuilt, "Yeah right!?" We all know how that turns out. After completely disassembling the engine it was determined that whoever rebuilt it had not done a very good job. As time and money allowed I slowly got the motor back together and I'm happy to say it runs extremely well now. First kick every time. I had started a build thread on a forum and called it The Low Buck Triumph because my goal was to see how cheap a whole bike could be built from the junk I already had, swap meet finds and spare parts ect. Well the naysayers on the forum were right it did not come in at what I had expected the cost to be because of having to freshen up the engine but I do not have a ton of money in it. I ended up using a few new parts to finish her off and I will say I'm fortunate enough to get a small discount for working here at the shop.

    I like it overall. Good job and I am a huge fan . My take. Front fender=YES Home Model 2" longer on the front paint or stainless=stainless ( I seriously can't tell the finish on the rear but match it) No oil filter = WTF!!

    I can live with the rest (rear shox=UGH). I do understand that the bike was built economically and for that 100% on fit finish and overall utility. Just a few PERSONAL nits. Your bike you like it I love it.

  • Great looking bike with great ideas. I am in the process of rebuilding a '65 Bonneville and love some of the ideas this bike offers. Thanks again Low Brow and Todd. We will be talking.

    From bits and spare parts around your garage, bike looks amazing. Recently picked up a 69 Bonnie. Bike is in good nick, just some issues with the carbs I think. Sat in garage for a couple of years without running. Anyway enjoy the YouTube feeds and blogs Lowbrow has. Cheers
