----- ------------ --------------
1st 2.353 6.8 39.2
2nd 1.667 9.6 55.3
3rd 1.286 12.5 71.6
4th 1.032 15.5 89.3
5th 0.853 18.8 108.0
Speed limiter 175kph = 108.75mph i.e. approx. peak power rpm
Approx rpm in top gear:
30mph - 1,600rpm
40mph - 2,130rpm peak torque at 47mph
50mph - 2,660rpm
60mph - 3,200rpm
70mph - 3,725rpm
80mph - 4,260rpm
* [Gear speeds calculated from above ratios and rear wheel and tyre size, i.e.
wheel diameter = 15in + (170mm * 0.80 * 2)/25.4 = 25.709in
circumference of wheel = 3.14159265 * 25.709 / 36 yards = 2.2435yds
after primary and secondary reduction 1,000rpm for an hour would give
(60 * 1000 * 2.2435 / 1760) / (1.66 * 2.875) = 16.026
hence 5th gear is 16.026 / 0.853 = 18.788 mph/1000rpm ]
