420 X-Ring Final Drive Chain Low Drag and Long Lasting Reliability for Surron LBX, Talaria Sting and E Ride Pro Includes connecting "master" link The X-ring has several advantages over the O-ring chain including: A standard O-ring, when squeezed between the inner and outer plates, deforms and has a large surface area An X-ring seal placed between the inner and outer plates twists as opposed to being squashed. This creates two smaller sealing surfaces with less friction and wear An X-ring distorts less than a standard O-ring, and the gap between the sealing surfaces does a better job of retaining grease Additionally, D.I.D. a well-respected manufacturer of dirt bike chains, that makes standard dirt bike chains, O-ring dirt bike chains and X-ring dirt bike chains indicates their X-ring chains last twice as long as their O-ring chains - roughly 20,000 miles vs. 10,000 miles. 420 size chains Fit Talaria sting MX3/4 Talaria XXX / XXX Pro Surron Light Bee Surron Hyper Bee Segway x260 79 Bike falcon M 79Bike Falcon Pro 79Bike Falcon GT E-Ride Pro SS 1.0 E-Ride Pro SS 2.0 E-Ride Pro S E-Ride Pro Mini Rerode R1 Rerode R1 Plus Rawrr Mantis X Yozma IN10 Strike Shadow Ventus One Ventus One Plus Tork Pro Sport - 120 Length Stock ETM RTR Sport - 86Links stock ETM RTR Alpha - 86Links stock ETM RTR XL - 96Links stock You will need a chain breaker (Purchase Here) if the chain length you need is not available Sprocket Size Surron LBX E-Ride Pro SS 2.0 Talaria XXX Talaria Sting MX3/4 79 Bike 42t 104 106 102 106 104 44t 104 106 102 106 (OEM) 104 48t 106 (OEM) 108 104 (OEM) 108 106 (OEM) 52t 108 110 106 110 108 54t 110 112 (oem 55t) 108 112 110 56t 112 114 110 114 112 58t 112 114 110 114 112 60t 114 116 112 116 114 64t 116 118 114 118 116
