Drive shaft assemblies (especially Japanese engineered types) are both reliable and durable over the longer term, and of course avoid the need for constant lubrication and adjustment that chain drives require.
But, eventually, you will experience drive line shunt when closing and opening the throttle, play between the shims will become more pronounced and possible lubrication leaks - but rarely a complete failure.
However, "a stitch in time saves nine", an old English saying, stating that early preventive maintenance could spare a whole heap of expensive trouble down the line.
Striping and inspecting the shaft drive assembly and the ancillary components would be a sensible winter task. Some of the parts you may require, apart from this component, are listed below.
Preventive maintenance can help avoid major problems down the line. Add as many items as you wish to the same shopping cart, new fasteners and seals for example, and still only pay the same single fixed price shipping cost. This component may have other applications within the Yamaha model range.
