K-Speed is one of the busiest shops in the business, turning out customs at a head-spinning rate. That’s because they’re also one of Thailand’s largest aftermarket parts suppliers, so they know a thing or two about production. Thier ‘Gorilla Racer’ is an in-house project for K-Speed themselves, and based on a 2019-model Monkey 125. The shop wanted to showcase some of their own catalog parts, and use the project as a test bed to try out some new concepts.
