My WP shock collapsed in Malaysia and I managed to get a YSS rear shock in 10 days to get me back on the road. Thirty odd days later it collapsed. Not happy as I'd given the weight stats and the abuse it was going to have prior to ordering. They sent a new one out, no questions, no charges, no returns and that got to me within the week, this lasted several months. Replaced that with a used OE showa unit which was still going strong when I sent the bike home.
This was the rear shock that was replaced.
Maybe someone got the weight factor wrong at the other end? They do look a good bit of kit.
