The Scottoiler V System is the latest edition of the market-leading range of vacuum-operated Scottoiler chain lubrication systems. The kit gives a range of approximately 400 - 800 miles between refills of the RMV (Reservoir Metering Valve), depending on the flow setting. The kit has a range of fittings suitable for most bikes, (non-standard adapters are available from Scottoiler), and includes a 250ml bottle of Scottoil, which should be enough for approximately 2500 miles of lubrication.
