Under the Microscope: Acme Loop Tail Frames

This is the frame EVERYONE who's seen one has been talking about. Our Acme Loop Tail frame is custom crafted in our own shop in Laconia, NH, to be the best and last chopper chassis you'll ever need.



The frame in these photos is built for Shovel and Evo motors with a 4-speed kicker transmission, but we offer our Loop Tail frame for Unit and Hinkley Triumphs, Yamaha XS650's and Evo Sportster motors, too.



The level of construction quality and attention to detail on Acme frames is unprecedented. Take for example our one-piece CNC-turned head tube with integrated steering stop and built-in bearing race seats. Every Acme frame comes with a lower stop that bolts to your fork tree and a matching stainless steel bearing cover on top to create a super-clean finished assembly. No more unsightly fork stops or weld-on tabs.



Our one-piece tranny plate is CNC machined from billet steel and precision TIG welded for beauty and strength. We offer both 4-speed kicker and 5-speed electric start plate configurations, so you can build your Acme chopper with any power train you desire.



The front motor mounts feature threaded bungs for forward controls, and the cross member is CNC machined for added precision. Raised engine mounting points can be sanded down after paint to allow perfect grounding between the cases and the frame.



The loop style axle blocks are CNC machined from a single piece of billet steel, and feature removable brass or stainless steel axle plates to protect the paint finish. The frame is wide enough to accept up to a 140 rear tire, and the rear triangle features our distinctive symmetrical design—no more offset tubes for belt clearance.



Every Acme Loop Tail frame comes with our precision-crafted alloy oil tank and battery tray (not shown). Our 6061 T-6 alloy oil bag features CNC machined mounting brackets and rubber isolation grommets with alloy inserts and 12-point chrome-plated mounting hardware. We think our Acme Oil Tank is the most beautiful and finely crafted aluminum oil bag for choppers and bobbers money can buy.

The MSRP on our all-new Acme Loop Tail frame starts at $2,400. When you add up all the style, function, quality and construction that goes into these American-made frames, we think the price is a value.
