1971 Triumph Bonneville Bobber

Todd of Small City Cycles from the city of Star, Idaho, United States, made available these pictures of his beautiful Triumph Bonneville Bobber which has a 1971 Triumph engine in a late 1960's Triumph frame with a bolt on hardtail. The Triumph vertical twin engine of this hardtail Bobber was punched from 650cc to 750cc by a Morgo big bore kit.

Todd: "I finished this bike a few months ago using 90% new parts with some original unrestored vintage parts in the mix for character. Everything has been rebuilt."

Todd: "Frame is stock 1960's front section with a vintage bolt on hardtail rear section. Frame has been powdercoated gloss black for durability. Actually, all the black on the bike other than the fork covers, tank and fender is powdercoated."

Todd: "Oil tank is a vintage vertical mount tank I was told came off an old Triumph drag bike. I left it the chrome as found and it really adds to the bikes vintage feel, plus I like the look of old chrome!"

Todd: "Motor is a 1971 Bonneville with a Morgo 750 big bore kit. Title matches the motor numbers. I am not the one rebuilt the motor but I did pull the top end and checked everything and it looked good. Pistons and cylinder walls were very nice. Valves looked great. I installed a new head gasket, pushrod tube gaskets, and rocker box o-rings and gaskets. Two brand new Amal carbs with brand new velocity stacks.

Brand new chrome dual lead coil with a Mity Max battery eliminator. Vintage cloth covered wire."

Todd: "Brand new exhaust head pipes, hangers and clamps. The rear "mufflers" (there is nothing in them...) are vintage and were not rechromed. I have not seen another set like them and have no idea what they came off of, just something I had in the shop. They have scratches here and there but are in nice shape, one of my favourite things about the bike."
