2020 GasGas TXT GP Lineup First Look: 4 More Trials Bikes

Just when we thought there would be only four GasGas observed trials motorcycles for 2020, GasGas announces the four-bike 2020 TXT GP lineup. The TXT GP models are an upgrade over the TXT Racing line (we just tested the 2020 GasGas TXT Racing 250).

The big upgrade for the TXT GP line is the suspension. The 39mm Tech fork is fully adjustable on the four GP models. As hard as it is to imagine, the Reiger 3V is a higher-spec shock than the Öhlins 2V used on the TXT Racing models. It is also fully adjustable.

Interestingly, the Tech fork on the GP models has 0.4 inches less travel than the Racing editions, while the rear suspension gains 0.4 inches of travel.

Additionally, the GP models have a carbon fiber airbox, compared to a plastic unit on the Racing models.

The 2020 GasGas TXT GP 125 is 1.4 pounds lighter than the TXT Racing 125, while the other three GP models are 0.8 pounds lighter than their Racing counterparts.

Otherwise, there are no other significant differences between the GP and Racing lines. However, there will be only 550 GP units produced.

GasGas has not announced an availability date or prices for the 2020 GasGas TXT GP lineup.
