Motion Pro - Rev2 Throttle Kit - YZ450F 14-15 - Superseded to 08-012960THE MOST ADVANCED VARIABLE RATE THROTTLE IN THE WORLD The Rev2 throttle has several different size reels that will change how much twist is necessary for the throttle to completely open the carbs or throttle bodies on a motorcycle. The larger the reel is, the shorter the twist. Each reel size will shorten the twist by about 10 degrees. If your stock throttle has a 40mm reel and stock twist is 90 degrees (1 4 turn), the 45mm reel will reduce the twist

Exact fit, no trimming needed
Style: One Piece
Ordered this for my Ford F-150 and it dropped right into the airbox perfectly — same dimensions as the OEM filter, same end seals, same fit. No gaps, no air bypass around the edges. Clean swap in under five minutes. Engine runs smooth and the price is unbeatable.

Great plug
Style: Single
My car goes through these every 30,000 miles or so. But fantastic plug all around. Performs flawlessly even at almost 9000 rpm.
