thunder conrods

[RDfella]

Was planning to change my GF conrods to new ones over the winter, as I don't trust alloy rods - especially old alloy rods.
Was considering Thunder rods. Feked refunded my order because they are out of stock, so I contacted thunder engineering direct. But can't get a reply. Anyone know if they're still trading?

I don't know if they are still trading, but I have their alloy rods and they've performed great (from my non-pro-motorcycle-mechanic perspective) for about 7,000 miles. You might try MAP Cycles.

i bought some thunder rods for the berger build, i have no idea if they still make them. on the other part of thinking my rods in the engine are from the 1950's and my bike gets a thraping hitting 6000 rpm on a regular basis, sometimes 7000 in first and second. but then again i am a nutter who makes it have it. don't be scared of old rods---- i'm not ----yet

G'day Richard.
The MAP rods are the same length as the R&R alloy rods (i have in the Cafe). Which are longer than the stock rods by about 0.030". Easy way to increase comp with flat top pistons.

I think they are still in business, they are based in leicester and this area has been on annual holiday for the last couple of weeks, so they may well be on shutdown

I'm pretty sure my alloy rods are Thunder sold by SRM some 10 years ago.

FWIW I fitted Thunder rods in my Commando and they worked fine. The only problem was they foul the engine cases and needed material removed. This information is available at RGM's website under 'Conrods'. I bought them as the standard rods have a bad reputation (and one ventilated my cases) although standard rods made recently will be better quality than those made in 1974.
