R stands for radial. This means that the core of the tyre is constructed using a belt made up of several steel plies. This makes for a more rigid tyre construction.
150 is the specified width of the tyre in millimetres
60 is the tyre's height aspect ratio. This means that the height of the tyre is 60% of its width, i.e. 150 x 0.6 = 90. So the tyre is 90mm high.
17M/C designates that the tyre�s inner rim diameter is 17 inches and so is designed to fit a 17 inch motorcycle rim.
66 marks the load index. This means this tyre can carry a maximum load of 300kg when inflated to the correct pressure.

H marks the speed index (SI). These tyres are rated to a maximum continuous speed of 130mph (210kph). Although the tyre is capable of achieving higher speeds, it cannot do so under its full load potential.
SI Chart:
J up to 62mph (100kph)
N up to 87mph (140kph)
P up to 93mph (150kph)
S up to 112mph (180kph)
H up to 130mph (210kph)
V up to 149mph (240kph)
W up to 168mph (270kph)
Z over 149mph (240kph)
