• H-Beam design for rigidity and strength

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.
