Description

Details

MAP Cycle is proud to offer our 4340 H beam connecting rods. The exotic 4340 forged steel makes for a lifetime rod.

Fits:

  • Triumph T120 Bonneville 650cc 1959-72 (all  years)
  • Triumph TR6 Tiger 650cc 1963-72 (all years)

Dimensions:

  • 6.50 inches center to center
  • .688 pin size

Features:

  • Rods are balanced to +/- 1 gram
  • Unmatched quality - the best rods available anywhere for Triumph
  • "Solid Works" designed and stress tested
  • Machined from 4340 forging
  • Shot peened for stress relief
  • 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

Finite element analyses 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 important weight reduction compared to other steel rods

Note:

  • Use with stock rod bearings, part number B2026M
  • Unlike the stock Triumph 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.
  • When trying to determine if these rods will fit your motorcycle or not, remember, that over this long a period of years, most bikes have been repaired many times. Later model heads and top ends are mated with earlier bottom ends and vice versa.  The only way to accurately determine what length rods you have on your bike is by measuring the crank pin journal dimension. The correct diameter should be 1.6235-1.6240.  The rod length, center-to-center, should be 6.5 inches.

I am rebuilding my 1966 T120R and need connecting rods. Do these rods weigh the same as my originals? If not, how does that effect my balance factor? Thank you, David Reid
