have a feeling this thread is about to change direction
The late, great Ray Ryans pet hate was modern riding gear on old bikes. He said that the plethora of colours and corporate branding took away from the look and feel of what our sport is about. I couldn't have agreed more. I have the usual (Moose) modern riding gear for when I'm riding my modern bike but I've gone out of my way to find safe yet era sympathetic gear for when I ride the old stuff.
I've been on a diet and my old gear doesn't fit any more so I bought a new pair of Metro Maico race pants for less than $100, an almost new pair of plain grey Sidii boots for $30 and have been buying all sorts of period Maico Jerseys for piss money. While I was at it I got a pair of Italian made plain black race pants that are far better quality than any of the American (Chinese) stuff you can buy. I got a Metro Martini jersey like Joel Robert used to wear and a Metro Ducati jersey. Helmets are a no compromise item though. I bought a new Bell Moto7 with Polaris snowmobile graphics for less than $200 and a Shoey open faced trials helmet for a similar price.
Its easy to look retro without sacrificing any safety if you shop carefully.
