Precision CNC machining for powersports: durable parts, built for performance

Powersports brands live and die by performance. Every component must be light, strong, repeatable, and available when the market needs it.

Basin Precision Machining partners with OEMs and Tier-1/Tier-2 manufacturers to deliver the precision-machined parts that keep your machines competitive and your customers riding.

Why powersports manufacturers choose Basin

• High-performance focus: We design manufacturing processes around fatigue life, weight reduction, and thermal stability—key drivers in engines, drivetrains, braking and suspension systems.

• Production at scale: From rapid prototype iterations to tens of thousands of parts, our workflows are built for repeatability and cost control.

• Aftermarket velocity: We help you serve a replacement-parts market that demands continuous availability, tight revision control, and consistent cosmetics.

Common powersports components

Engine & induction: Throttle bodies, intake manifolds, cylinder head and block features, covers, cam carriers, pump housings, impellers, pulleys, valve train components.

Drivetrain: Transmission/differential housings, shifter forks, shafts, sprockets/gears, hubs, carriers, yokes, clutch baskets and pressure plates.

Chassis & suspension: Triple clamps, steering knuckles, control arms, linkages, subframes, pedal sets and foot pegs, brake caliper bodies and brackets.

Controls & accessories: Master cylinders, handlebar clamps, rearsets, steering dampers, throttle/shift components, mounts and brackets.

Water & snow: Jet-pump parts, wear rings, impeller nuts, pump stators, track-suspension hardware.

Light aviation & specialty: Machined brackets, housings, control system parts, lightweight structural fittings.

Examples of parts we are ready to produce:

• Billet triple clamps and bar risers with weight-relieved pockets.

• Brake caliper bodies and brackets with tight bore concentricity.

• Transmission housings and shifter forks with wear-critical profiles.

• Sprockets, hubs, carriers, and lightweight subframe nodes.

• Jet-pump and impeller components for PWCs.

• Pedal sets, rearsets, and linkage systems optimized for stiffness-to-weight.

The powersports industry is relentless

The powersports aftermarket is relentless: riders and racers need fresh parts every season—sometimes after every weekend. We align your supply chain with that cadence.

• Repeatable reorder runs: Locked programs, fixturing, and inspection plans let us re-launch production quickly for spares and service kits.

• Lot-level serialization & traceability: Clean part genealogy for warranty, racing tech inspection, and regulatory needs.

• Cosmetic consistency: Uniform finishes and engraving for retail-ready aftermarket components.

• Forecast-friendly scheduling: Kanban, blanket orders, and safety-stock strategies that keep shelves full without tying up cash.

Technical capability that translates to lap times

5-axis milling and multi-axis turning

Complex, topology-optimized geometries aren’t a problem. Our multi-axis strategies reduce setups, protect geometric datums, and hold true position on intersecting bores and blended surfaces—crucial for caliper bodies, throttle bodies, and gear housings.

Typical results:

• Positional accuracy to ±0.0127 mm (±0.0005 in) on critical features.

• Surface finishes to Ra 0.8–1.6 μm on sealing faces and sliding fits.

• True-position on bolt circles and bearing seats maintained through production.

Materials expertise for harsh environments

We routinely machine and validate performance alloys used throughout powersports:

• Aluminum: 6061-T6 for general structural, 7075-T6 for high-strength clamps, hubs, and subframes.

• Steels: 4130/4140, 8620, 1018/1020 for shafts, gears, and welded structures.

• Stainless & precipitation-hardening: 17-4 PH, 15-5, 304/316 for corrosion-prone assemblies (PWC, snow).

• Titanium: Ti-6Al-4V for strength-to-weight critical parts (fasteners, pedal sets).

• Copper alloys: C630 (aluminum bronze) for wear components and bushings.

We integrate heat treatment, shot peening, hard coat/anodize, nitriding, zinc-nickel and phosphate finishes via qualified partners, with controlled certification and traceability packages.

Metrology and process control

• CMM and in-process probing validate datums, bore alignment, and complex profiles.

• SPC on critical characteristics ensures capability across the lot—gear tooth runout, bearing fits, and sealing land flatness stay inside control limits.

• Tool presetting and offsets management shorten setups and lock in repeatability for production volumes and replacement runs.

Manufacturability & weight optimization

Our engineers participate early with design-for-manufacturability (DFM) to reduce part count, convert welded fabrications to single-piece billets where it helps fatigue life, and apply cost-saving machining strategies (e.g., near-net castings/forgings where appropriate). Expect guidance on wall thickness, fillet radii, tool access, and fixturing to hit both strength and weight targets.

Keep your riders moving

Your customers expect precision, reliability, and speed to delivery. We bring the equipment, process discipline, and powersports know-how to make that real—part after part, season after season.
