Why a billet 428 sprocket for the Pro-SR and Pro-SS 3.0?
Heavy Hitter built the 428 Super Sprocket for high-torque e-motos running a 428 chain, and for riders with big power upgrades who need a sprocket that handles the load without bending. Its experience is that these sprockets bend from sheer torque on hard landings rather than from hitting objects, which sends riders back to heavy OEM steel just to stop throwing chains. The 428 Super Sprocket is machined from a single piece of 7075-T6 aluminum to stay as light as possible without losing structural integrity, with beveled edges for smooth chain engagement and a black anodized finish.
Which bikes need the M8 sprocket bolt kit?
The product page requires upgraded hardware for four of the fitments: the Arctic Leopard XE Pro S, XE Pro R and XF Pro, and the Talaria MX5. For those bikes, order the Heavy Hitter Stainless Steel M8 Sprocket Bolt Upgrade Kit alongside the sprocket for proper fitment. The E Ride Pro-SR, Pro-SS 3.0 and Pro-SS 4.0 and the 2024-onward Rawr Mantis X Pro carry no such requirement on the product page.
How was the 428 Super Sprocket validated?
Heavy Hitter tested the rotational load case in CAD, then validated the part in real-world riding that included full-throttle landings and object strikes. Re-gearing with a different tooth count also reduces the load on the stock motor and controller when running heavier wheels and tires, and the seven sizes from 48 to 60 teeth cover that range.
Which sprocket fits the 420-chain bikes?
The Sur Ron Light Bee X, Segway X160 and X260, Talaria Sting MX3 and MX4, E Ride Pro-S and Pro-SS and the other 420-chain models use the Heavy Hitter 420 Billet Aluminum Super Sprocket, which has its own specs page.
