Hi,

My restoration continues, and will soon need to get the drive bits sorted. Obviously, sprockets are worn / toast, so am replacing the whole trifecta.

I'd like to replicate what the previous owner had - 14T (OEM?) front, a really nice Supersprox 50T rear, and a high quality gold chain (not sure of the brand, DID, I suspect).

I'd like to avoid buying stuff piecemeal - looking for a good combo that gets me as close to the above spec as possible. This seems to be the one to beat -

any other ideas for achieving this or a similar spec combo?

Non negotiables = 14/50
Highly prefer = blue colour, and high-longevity rear sprocket, high quality chain.

thanks,

c

I'm fairly sure Dirt Tricks Iron Man sprockets are made that fit: KTM Zirconium Rear Sprocket ? Dirt Tricks

These basically ... don't wear.

Last time i bought chain and sprockets, I went with a DID 520VX2 chain and an Ironman front/rear set, both off Amazon. My goals were the same as yours there. Tried to do my research. Happy with what I bought.

Thanks Tourist.

I'm seeing all 14/50 Ironman + chain kits out of stock.

Any other sources/ideas?

thanks,

hmm! I’d consider nearby f/r tooth counts that have less numeric factors in common - in other words, 14 and 50 are both divisible by 2, so the chain hits the same teeth more often. 14/49 or 14/51 have no common factors, which is supposedly a slight advantage for chain life. The 550 being a ridiculously powerful bike, I’d go for 14/49; No discernible difference to rider but 2% less revving

If you buy the kit directly from Supersprox, you get a lifetime warranty (and a free t-shirt).

Lifetime? Supersprox last about a month on my bike.
Ironman 5 years and counting.
