Why DFC
Built around the rider—not a generic setting.
DFC Suspension was founded in 2021 by Rob Simmons, but the foundation started long before the business name existed. A lifelong focus on motorcycles, fabrication, hydraulics, engines, and suspension development shaped the shop into what it is today.
Every build combines rider feedback, mechanical inspection, tuning experience, and dyno-verified data where applicable. Individual rider files and build records keep the work connected to the rider, the motorcycle, and how it is actually used.
