In another Dirt Bike Rider/Toofast special talk ‘n’ ride video, DBR’s excitable test pilot, Ed Bradley takes the DBR long-term tester – Yamaha YZ450F – out for a spin in our monthly mission to improve upon this already remarkable machine.

This time we have attached an Akrapovic exhaust system… you’ll have to watch to find exactly what Ed makes of the new exhaust!

Check out the June edition of Dirt Bike Rider magazine for an extended test of this product (and many more!). Enjoy…
