RZ/RD 350 & Misc. 2-Stroke Tech BBS

Hi WFO ALWAYS, I am afraid that the last pair were sold on 08th Aug 2022. I did post a notice on this forum on 10th Feb 2021 saying that there were 3 pairs remaining and that I would no longer be manufacturing the caliper adaptors. Unfortunately I am no longer in a position to produce these caliper ...

Note to all,

My grateful thanks to all those that have bought the adaptors from me, your purchases have been much appreciated.

Kind regards, Norman.

I still have 3 pairs available. (See my previous post above).
Stay well, ride safe, Best regards, Norman.

If you are interested in purchasing a pair of adaptors, the cost would be USD$245.00 for 1 pair (1 left hand & 1 right hand) wh...

Yes, they are still available.
Please see my PM sent to you.

Cheers, Norman.

The original early RZ350 rotors are 267mm diameter. Early R6 and R1 rotors are 298mm diameter.
Therefore the size difference is 31mm in diameter.

A friend of mine in Albany, Western Australia very recently commissioned me to make up a set of caliper mounting brackets. The modification has been to fit early R1 disc rotors (298mm dia) to early RZ350 wheel and forks, using Yamaha R1 'Blue Spot' or 'Gold' calipers. The early RZ350 forks have a no...

For a number of years now, this old SR500 has been an ongoing project to breathe some new life into it. I acquired it as a pretty scruffy looking machine that had been flogged daily as a commuter bike by the previous owner. My intention is to turn it into a Cafe Racer style 500, based on the look of...
