The minimum pressures for 3.25 x 19 tyres are 16-lbs. front and 18-lbs. rear, and are sufficient for a solo rider of average weight.

The carrying of a pillion passenger will make additional pressure in the rear tyre essential, and also the adjustment of the rear suspension should be altered.

Pressures for extra loads are as follows :

Load in Pounds Pressure in Pounds per Square Inch
200 16
240 18
280 20
350 24
400 28
440 32
