The speed controller – your tool for victory
The speed controller in classic black look with red buttons positively invites every driver to burn some rubber. As usual, you'll find the accelerator button on top. With precision accuracy and a healthy dose of instinct, you’ll master every corner at the right speed. Another button is positioned to the front. This is the high speed turbo button that takes you past your opponent when on the long straight. Its ergonomic design and precise controls allow fast lap times, so you are well prepared for long distance races. The speed controller can be used in conjunction with the connecting tracks (61666 or 61662).
