Ultratwister was a steel roller coaster model manufactured by the now defunct Togo. It was the first working and only successful pipeline roller coaster.

When it debuted in 1984, the Ultra Twister was the steepest roller coaster in the world. It is believed the Ultratwister was acquired by Premier Rides, who list the product on their website.Citation needed



Togo offered two variants of the Ultratwister. The most common variant features a tilting track section after the first heartline roll. The car is stopped on this track section facing forwards and is tilted such that the car can now roll backward. Two more heartline rolls follow, taken in reverse. There was only one installation of the second variant built. Instead of the tilting track section, it has a dive loop. Because of this, the final two heartline rolls are taken facing forwards.


7 cars. Riders are arranged 2 across in 3 rows, for a total of 6 riders per car.
