Frame Shop

We have more than 1,200 frame variations for Harley-Davidson® motorcycle engines! Whether you’re trying to build a Twin Cam-powered Bagger or a Bobber with a flathead 45, Paughco can do it.



We offer the largest line of Springer front ends in the industry. Paughco’s narrow, wide, and wide shock Springers meet every need and application. Second to none in quality and style, our Springers come fully assembled with a 7/8" or a 1" neck stem, and a Dog Bone or Glide-Style top clamp. Special features include straight, twisted or wishbone front legs, and tapered oval rear legs. Each Springer is hand crafted and dipped in Paughco's award winning chrome finish.



Old-STF Cycle is a family owned shop located in Northern California. The father and son team of Rick and Mike Pilaczynski realized their dream of owning their own shop after many countless years working as mechanics at a power plant. One day they decided they'd had enough and Old-Stf was born. Now, along with owning a retail shop and building bikes, Old-Stf manufactures a line of parts and accessories in the USA. Old-Stf is your "Mom and Pop" type of shop and a place to learn, laugh and be inspired.
