Today’s update follows a similar pattern, with several improvements to off-road driving physics, including improved suspension systems, a new off-road tire pattern, new rider motions and animations, and the ability to to perform tricks in the air such as whips and backflips.

The update also adds a new track with three layouts and updates the Hurricane Mills circuit using real world data. As for the bikes, two motocross bikes have also been added and come with an all-new sound design.

Antelope Valley MX

Antelope Valley, or AV Motoplex as it was known, is a former motocross venue in Lancaster, California that closed in 2015. Featuring three layouts, the circuit is mostly loose dirt with a host of small jumps interspersed with passable tables and berms. .

TrackDayR has three configurations for Antelope Valley MX: Main, Vet and Mini. Mini, or the Peewee layout as it was called, was more suited to younger riders, while the Vet and Main courses are longer and have bigger jumps and berms to tackle.

Located in a relatively flat area of ​​the Golden State, AV Motoplex has been completely torn down and replaced with several self-storage facilities. Shame.

Antelope Valley is pretty straightforward – it’s a man-made motocross track after all

MX125 2 Stroke and MX250 4 Stroke Motorcycles

The MX125 and MX250 are two of TrackDayR’s new unbranded motocross bikes. 125cc motocross bikes are not typically used for high-level motocross competition, but are instead the ideal starting point for adults new to the sport. They are, however, an excellent step forward for young riders wishing to move up from the 50cc/85cc categories.

The MX250 motorcycle simulates the type of motorcycle used in the MX2 class of the FIM Motocross World Championship or the 250cc Motocross class in the AMA Motocross Championship, bridging the gap between 450cc and 125cc motorcycles in the game.
