K75-S replacement shock

I bought my ‘92 K75-S in ‘94 with 2,000 miles. It’s been garaged and well kept and I’ve only ridden it 10,000 more miles in 31 years so it’s mint but the OEM rear monoshock started leaking oil and needed replacement. The guys at Ted Porter’s BeemerShop recommended this shock and OMG!!! The bike rides waaaaay smoooother than when it was new. Soaks up small bumps like they’re not even there and handles way better in the turns. OEM shock was linear and this YSS spring is progressive (and more modern overall). And Ted Pirter swapped out the stock progressive spring for a lighter one b/c I only weigh 160 lbs. The improvement is just fantastic, and worth every penny, especially since it comes with their amazing (free) initial phone consultation/ advice, and they stand behind it.
