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:

  • BSA A50 (1962-70) all models including Royal Star, Cyclone, Clubman,
  • BSA A65 (1962-72) all models including Lightning, Rocket, Thunderbolt, Firebird, Spitfire and Hornet
  • BSA A70 (1971-72) Lightning,

Features:

  • Sold in matched 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:

  • Use with Stock BSA Rod Bearings B2046M
  • Unlike the stock BSA rods, these rods have been designed without a big end oiling hole because it is not necessary. Other oiling systems take place of the hole in the big end.

Just a word of appreciation.
Thanks for making these excellent rods available at such a reasonable price. We have them in a 90degree big bore 750. They are lighter than some aftermarket alloy rods and balance well, this is the smoothest A65 we've ever built. Review by Mark Parker Australia. / (Posted on 11/19/2018)

I am interested in the MAP rods for my A65. I'm in need a new set anyway and these look good. I'm wondering if these rods have an oilier hole on the drive side boss? Also, is there much drama in getting the crank balanced?
