Over the past several years, we’ve seen happy to see muscle bikes gaining ever more traction in the customs world. These machines offer big torque, intimidating presence, and staggering straight-line performance, often paired with styling that emphasizes mass and aggression over delicacy: wide rear tires, exposed engines, and minimal bodywork. Displacement generally starts at 1000cc, and V-twins, V-fours, and inline-fours are the most common engine layouts — often with nitrous or forced induction.
Events like the UK’s Worship Moto Show have popped up to showcase such machines, replete with big-bore vintage superbikes, streetfighters and Spondons, drag bikes and turbo weapons. We featured a number of these bikes this past year that garnered massive traffic and engagement, so we decided to present a list of the Top 10 Muscle Bikes & Streetfighters of 2025 based on traffic and engagement data. Not all of these machines fit neatly into one of these categories, but their popularity with our readers warranted their inclusion.
Stay tuned for our Editor’s Choice Top 10 — a more subjective list of our favorite features of the year.
