Product description

Superior design, superb craftsmanship and the best materials make this the best rod available for Triumph or BSA 250cc singles!

Fits:

  • Triumph TR25 (1968-70)
  • BSA B25 (1968-72)

Dimensions:

  • 5.312 center to center
  • .688 pin size

Features:

  • Ultra-high quality, manufactured from exotic 4340 forged steel
  • Unlike alloy rods, this is a lifetime rod
  • Not effected by heat cycles like alloy rods
  • H-Beam design for rigidity and strength
  • "Solid Works" designed and stress tested
  • Shot Peened for stress relief
  • Includes race-type ARP2000 Bolts (220,000 lb. tensile strength)
  • Innovative machined piston oil squirting notches
  • Double Wrist Pin Oilers
  • Unique Reinforced small end critical areas without adding excess weight or cost
  • Use with Stock Triumph Rod Bearings B2047M

Finite element analyzed design by High Cotton MotoWorks allows for:

  • Re-shaped pin boss for added strength (helps prevent "pin flex"& small-end failure)
  • Double “Forced” pin oilers to reduce friction and piston pin heat
  • Bushed small end (replaceable) eliminating the need for fragile and expensive DLC pins
  • Optimized big-end and pin boss for strength with the ALL important reduced weight compared to other steel rods

Note:

  • Unlike the stock Triumph/BSA rods, these rods have been designed without a big end oiling hole because it is not necessary. Other oiling systems make the oiling hole in the big end unnecessary.
