Description

Details

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

Fits:

  • Triumph T120 Bonneville 650cc 1959-1972
  • Triumph TR6 Tiger 650cc 1963-1972
  • Triumph pre-unit models 1956-1962  (for earlier models - see "Note" below)

Dimensions:

  •  6.50" 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 O.E.M rod bearings, part number B2026M
  • Designed to fit all standard  650 T120/TR6 engines from 1959-1972
  • For 500/650 pre-unit engines prior to 1956 models, it is best to measure the big-end journal diameter and rod length prior to ordering as many early small journal cranks have now been replaced with stronger ones from later model engines.  Verify that your crank has a journal diameter of 1.6235"-1.6240" (standard) and a rod C-C of 6.5" prior to ordering.
