Boyesen Pro Series Reeds
GUY in NJ
Quality product
I use these reeds currently on my YZ250 and all my 2 strokes I've had in the past. Crisp throttle response and they last. You can't go wrong with Boyesen.

Boyesen Super Stock Carbon Reeds
Facundo in FL
Excellent, best option to replace OEM
Excellent . best option if you have to replace your stock reeds without spending a lot. My OEM reeds were in good shape so, i didnt feel any difference in performance . Bike is running strong with boyesen reeds, excellent fitment

Boyesen Super Stock Fiber Reeds
Travis in WY
Crisp throttle response and smooth intake airflow
Swapped these into the reed cage to replace worn factory petals, and they made an immediate difference in throttle response. The fiber material is durable, lays perfectly flat against the cage seating surface, and seals tight to prevent air leakage. They open and close efficiently across the powerband, giving you snappy acceleration down low without fluttering out at higher engine revs. Simple bolt in upgrade that restores crisp intake performance and keeps the engine running strong.

A stylish replacement
I didn't realize just how worn and dated my last lines made my intake look. The purple looks sharp against KTM orange

Good replacement tubing
Worked great on my sons Yamaha wr250. Only problem is I had to order a second roll. 1 roll is not even close to enough.
