EVO Factory 300 2-Stroke

Category Tag

The 2025 EVO Factory range represents Beta’s most refined trials bikes yet—developed alongside World Trial team riders and engineered to deliver the precision and control that many call the “Gold Standard” in trials.

What’s New for 2025

A major update comes from the new suspension package:

  • New larger-diameter front fork for a more planted, precise front end and easier adjustability
  • Upgraded aluminum-body rear shock for lighter weight and improved performance

Factory-Only Engine Upgrades

  • Magnesium crankcase (black finish) saves over 3 lbs while adding a factory look
  • Trimmed clutch discs for sharper feel and better control during repeated high-rpm moves (hops, big steps, etc.)
  • Black anodized oil filler plugs
  • Titanium exhaust
    • 250/300: more than 1.3 lbs lighter with stronger mid-to-top rpm pull
    • 125: unique internal design to boost low-rpm torque and quick acceleration

Chassis, Suspension & Component Upgrades

  • New 39mm Factory fork (1mm larger than before) increases rigidity and steering accuracy
    • single-sided spring design + dedicated damping leg for faster response and weight savings
    • larger hard-anodized cartridge rod
    • external adjusters for damping + preload
    • TiN gold coating for reduced friction and premium Factory look
  • Blue anodized billet triple clamps, lighter than standard, with adjustable bar mounts
  • Blue oversized Reikon handlebar
  • Black billet footpegs with steel pins for maximum grip
  • Blue wheels + tubeless rear tire for traction
  • Black anodized chain adjusters + handlebar end plugs
  • Red silicone radiator hoses
  • Rear sprocket cover/decal + handlebar tether (rule compliant)
  • Galfer racing brake discs, BrakTec master cylinders, anti-vibration rear caliper
  • Michelin X-Light tires
  • New MY2025 graphics: matte grey frame with aggressive blue/red Factory accents

Fit Tip

Factory models are more responsive and race-focused, so many amateur riders will feel best by stepping down one displacement—for example, a standard 300 EVO rider may prefer the overall feel and control of a 250 EVO Factory.
