RSI “STONEWALL” HANDGAURDS FLEXIBLE, ALL WEATHER HANDGUARDS

Ultra-durable, flexible, and weather-resistant handguards that expand coverage for maximum protection in extreme riding conditions. Designed to move up, down, left, and right with a unique RSI mounting system for unmatched adjustability and performance.

RSI Stonewall ExtremeFlex Universal Handguards

Built for Extreme Conditions. Designed for Total Protection.

When the weather turns brutal and the terrain gets unforgiving, your hands shouldn’t take the hit. The RSI ExtremeFlex™ Handguards are engineered to deliver superior coverage, unmatched durability, and extreme weather protection across multiple riding platforms.

Unlike traditional rigid handguards that crack, crush, or warp under pressure, RSI’s proprietary flexible construction absorbs impact without deforming — maintaining its shape and performance ride after ride.

Maximum Coverage. Total Control.

The RSI ExtremeFlex™ system expands outward to provide increased wind and weather protection, shielding your hands from:

Snow
Rain
Sleet
Mud
Roost
Trail debris
Freezing wind

Whether you’re climbing mountain terrain, blasting across a frozen lake, navigating tight ATV trails, or carving water on your PWC, these handguards adapt to the elements.

4-Way Adjustable Mounting System

What truly sets RSI apart is the exclusive mounting position design.

With the required RSI mounting brackets, riders can adjust positioning:

Up
Down
Left
Right

This allows you to dial in the exact fit and protection angle based on riding style, weather conditions, and machine setup.

No fixed positioning. No compromises. Just precision fit and customizable coverage.

Flexible. Durable. Virtually Indestructible.

RSI ExtremeFlex Handguards are engineered to:

Resist crushing
Prevent warping
Withstand impacts
Maintain flexibility in freezing temperatures
Hold shape in high heat
Perform in wet or dry conditions

These handguards are built for riders who push limits — from backcountry mountain snowmobilers to aggressive off-road ATV riders and watercraft enthusiasts.

Multi-Platform Compatibility

One system. Endless applications.

RSI Handguards work great on:

Snowmobiles
ATVs
Personal Watercraft (PWC)
Crossover Bikes
Mountain Bikes
Custom powersports builds

Their universal adaptability makes them one of the most versatile handguard systems available.
