DNA Adventure Expedition Kit Stage 2 for BMW R 1200 / 1250 GS / 1250 RT (2019-23)

The DNA Adventure Expedition Kit Stage 2 for BMW R 1200 / 1250 GS / 1250 RT (2019-23) is a high-flow air intake upgrade designed for Road and Off Road use. The Stage 2 kit replaces the standard BMW air filter and its restricting plastic frame.

DNA developed this kit to improve airflow through the factory airbox. Its lower filter position frees the two air passages that direct cold air from the front of the motorcycle. As a result, the design helps reduce restriction and turbulence while improving airflow towards the lower airbox. Visit our website for more products Dirt Street. 

Advanced Stage 2 Adventure Expedition Design

The DNA Adventure Expedition Kit Stage 2 features DNA’s advanced FCd (Full Contour design). Unlike the standard replacement filter, this Stage 2 system replaces both the stock air filter and the restrictive plastic frame.

The filter sits lower within the airbox. This position frees the two airflow passages that direct incoming cold air toward the filter. Therefore, the incoming air can move more smoothly toward the lower airbox.

38.50% Increased Airflow

One of the key benefits of the DNA Adventure Expedition Kit Stage 2 for BMW R 1200 / 1250 GS / 1250 RT (2019-23) is its increased airflow.

The DNA Stage 2 Adventure Expedition Kit delivers 181.40 CFM, compared with 131.00 CFM from the BMW stock air filter. This represents a 38.50% increase in airflow over the standard filter.

The increased airflow and revised filter position help reduce restriction and turbulence. DNA states that the design can improve torque and power.

80% Larger Filtering Surface

The Stage 2 Adventure Expedition filter features an active filtering surface of 132,300 mm². This provides an 80% larger filtering surface compared with the standard replacement air filter.

Furthermore, the larger filtering surface can extend the filter service intervals. This allows riders to travel longer before cleaning the filter, which can be particularly useful for longer road and off-road journeys.

98%-99% Filtering Efficiency

Despite its larger filtering surface and increased airflow, the DNA Stage 2 filter maintains a high 98%-99% filtering efficiency.

The filter uses four layers of DNA cotton. Therefore, the kit combines increased airflow with effective filtration for Road and Off Road use.

Road and Off Road Use

The DNA Adventure Expedition Kit Stage 2 is designed for both Road and Off Road use. Its increased filtering surface and airflow make it suitable for riders who cover different types of terrain.

Moreover, the larger filtering surface can allow longer intervals between filter cleaning. This can be useful during extended journeys where regular filter maintenance may not be convenient.

Fuel Recalibration

DNA recommends fuel recalibration for this Stage 2 application. With the appropriate fuel recalibration, DNA states that the results can be very impressive.

Therefore, riders should consider the recommended recalibration when installing the Stage 2 kit.

Why Choose the DNA Stage 2 Kit?

The DNA Adventure Expedition Kit Stage 2 for BMW R 1200 / 1250 GS / 1250 RT (2019-23) offers a revised approach to airflow management. It replaces the stock filter and restricting plastic frame while positioning the filter lower in the airbox.

As a result, the two cold-air passages become less restricted, while the larger filtering surface provides increased airflow. The kit delivers 181.40 CFM, representing a 38.50% increase over the OEM filter.

At the same time, the filter maintains 98%-99% filtration efficiency. Its 80% larger active filtering surface can also extend service intervals between cleaning.

Conclusion

The DNA Adventure Expedition Kit Stage 2 for BMW R 1200 / 1250 GS / 1250 RT (2019-23) is designed for riders who want increased airflow for Road and Off Road use. Its Stage 2 design replaces the standard filter and restricting plastic frame while freeing the two front air passages.

With 181.40 CFM airflow, an 18.50%? increase—correction: 38.50% increase—and 98%-99% filtration efficiency, the kit provides a significant airflow improvement over the BMW stock filter. In addition, its 80% larger filtering surface can help extend service intervals. Fuel recalibration is suggested for this application.
