KKE 21/18 All Black Wheel Set for Sting MX3

Swapping the MX3's stock 19-inch front and 17-inch rear for a 21/18 pair puts the bike on standard motocross wheel sizes, which opens up the mainstream enduro and MX tyre catalogue from Maxxis, Dunlop, Michelin and everyone else without adapters or conversions.

KKE builds this set with aluminium hubs, stainless steel spokes and aluminium nipples, anodised black throughout. It is the leaner-priced alternative to a Warp 9 set, and the trade-off is straightforward: no rotor and no sprocket in the box, so both come off the stock wheels or get bought separately. The rims are tube-type only — inner tubes are needed, and tubeless conversion is not supported.

Primary fitment is the Sting MX3. Sting R MX4 owners should check hub bore, axle width, disc offset and sprocket-side spacing before ordering; the two chassis are similar but not guaranteed identical.

Installation is moderate, around 45 to 60 minutes per wheel with an axle wrench, torque wrench and tyre irons if tyres are going on at the same time. Balance both wheels before the first ride and re-torque the axle hardware after the first hour out. Shipping runs from China with regional warehouse support, usually 3-5 business days.
