Wide Ratio Transmission Gear sets

For hair scramble, desert, woods and flat track racing the first gear on the CR500 and Cr250 is too tall. Gearing it down can help, but will reduce top speed. To cure this problem Madman Engineering  offers a wide ratio enduro transmission kit that spaces out third, fourth and fifth gears.

The stock cr250, & cr500 Ratios are:
1st: 1.8 2nd: 1.47 3rd: 1.235 4th: 1.05 5th: .909
The new Madman ratios are:
1st: 1.8 2nd: 1.47 3rd: 1.1 4th: .909 5th: .75

Cr250 02 - 05 (needs pre 02 countershaft & shims)

Cr250  86 - 96

Cr250 96 - 01

Trx250r  87 - 89
