Description

Details

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

Fits:

  • Triumph T140 Bonneville 750cc 1973-88 (all  years)
  • Triumph TR7 Tiger 750cc 1973-82 (all years)

Dimensions:

  • 6 inches center to center

Features:

  • Sold in pairs - 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:

  • 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.

Product Question

Product Questions

Question will be displayed after moderation.

Dear Map, I have been looking at your website with interest at your steel con rods for Triumph T140, my question is, are the wrist pin bushes already honed to size and ready to fit, so to speak, or do they require honing to size to achieve the correct wrist pin clearance, as with carrillo rods ? also would you mail me the correct code for a STD set of big end shells to suit 1973 T140v, and your con rods.

Hi, will standard Triumph big end shells (70-3586/000) fit these rods, or do I have to use the MAP shells?
