TRANSMISSION CHAIN TENSIONING AND LUBRICATION
Models MRX – MSX 125 are special because they are fitted with chain tensioning mechanisms which
always maintains the chain at the correct tension.
The chain tension can be adjusted by means of eccentric mechanisms mounted on the rear wheel axle,
always operating at the point of maximum chain tension. Rotate the rear wheel several times and check
that the tension at several point in order to locate the point of maximum tension, pulling the tensioning
mechanism downwards to prevent this operating while the checks are being performed.
