The ingenious solution for changing up without the clutch! An electronic sensor registers the precise time at which the shift lever is applied for shifting and interrupts the ignition for a split second. This allows upshifting without resistance, without using the clutch and without closing the throttle. Also for use with reverse gear change kit 69034931066. Requires mounting kit 69034081044 for MY 08-10 or 69334981033 for MY 11-13.
