Determining what these numbers mean on ohlins shock (21040-31/95 L496)
----------------------------------------------------------------------------------------
When looking at your spring you'll notice a set of numbers, example (21040-31/95 L496). The first few number determine the length on the shock (21040) normally 160mm is standard, and the next few number relate to weight ratio for riders(-31/95). Ohlins uses its own numbers. which is where things can get confusing figuring it out. Only concern yourself with the second number /95 in this case. The last set of numbers (L496) relates to the lot number. Below, the chart has it broken down into weight, and total recommended weight capacity for your bike and rider.
