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.

Service process

A Rider-Focused Motorcycle Suspension Service Process

The recommendation begins with the rider and the job—not a generic setting copied from another motorcycle.

01

Define the job

We document the rider, motorcycle, discipline, terrain, pace, current feedback, and setup goals.

02

Inspect & document

Forks, shocks, chassis condition, measurements, current settings, and required service scope are inspected and documented.

03

Build & verify

Components are serviced, tuned, assembled, and dyno verified where applicable.

04

Return with a baseline

The motorcycle returns with documented settings, build records, and a clear baseline for rider feedback.

Suspension Maintenance

Motorcycle Fork & Shock Service Intervals

Recommended intervals apply to both fork and shock assemblies unless a shorter model-specific interval applies.

Moto and off-road15 operating hours30 operating hours
Moto and off-road racers10 operating hours20 operating hours
BDR / adventure off-road15 operating hours30 operating hours
Track-only – sportbike and supermoto15 operating hours30 operating hours
Adventure – predominantly pavement10,000 miles20,000 miles
Street15,000 miles30,000 miles

Service Cycle: Seal service / rebuild occurs every second complete oil service.

Complete Oil Service

Fork service includes all applicable oil chambers and cartridges. Shock service includes disassembly, cleaning, bleeding, and nitrogen recharge.

Seal Service / Rebuild

Includes complete oil service, full disassembly, cleaning, seal replacement, inspection, and applicable wear components.

Classification

Adventure motorcycles used primarily on pavement follow mileage. BDR-style adventure off-road use follows operating hours.

Override

Shorter model-specific manufacturer intervals and condition-based requirements take precedence. Leakage, contamination, crash damage, fade, or abnormal operation require immediate inspection.
