Product Details
DPYR flyweight for Yamaha snowmobiles
The DaltonPro DPYR series uses a curvature that is slightly less aggressive than our DPY flyweights. This new curvature allows more “untucked” mass at the point of belt contact and allows for the use of more total flyweight mass than many aggressive flyweights. These 4-stroke oriented flyweights can offer quicker acceleration while still maintaining excellent low speed belt grip. Uses factory Yamaha mass rivets for adjustable tuning. Typical applications use 58 to 62 g base weights on RX/Apex applications, while many turbocharged tuners use the 70 and 74g base weights in configurations to 83g total mass.
