News for 2019


2019 marks a new quest for the Kawasaki brand to own the 450cc motocross class. 
By the looks of it, the new big bore green machine looks like a strong contender.

At Yoshimura, we saw an opportunity to make the new green offering live up to its potential. 
Power and torque is up across the entire range for both curves with the new KX! 
Max HP is up an incredible 3% and max torque is up 4.3%. 
The heart of the power is our RS-4 muffler with its Polyresonant Duplex front chamber and 
added overall volume helps make the 2019 KX450 come alive.



Brand new from KTM and Husqvarna for 2019 are re-vamped 250 SX-F / FC250 and SX-F 350 / FC350.

Both the 250 and 350 make good HP and torque in stock form, 
but nevertheless we went to work to improve power in every RPM range on these twin race machines and 
the gains we were able to attain with our RS-4 are quite impressive.

We wound up with the 250 peak HP at 6.6% and a big gain of peak torque of 14.2%. 
The 350 was even more impressive with a peak HP gain of 10.2% and peak torque gain of 7%. 
The work horse for much of this performance is our RS-4 muffler. 
With its Polyresonant Duplex front chamber to add overall volume, 
and the special stepped two-stage baffle configuration that reduces sound without restricting performance. 
These Austrian 250 and 350 race machines are ready for the top of the podium now!
