Product Description Corghi Motorcycle Upgrade Kit 19mm — Part 8-21120013 This is the large-bore half of Corghi's motorcycle balancing setup. The base motorcycle package covers scooters and the smaller hub bores; this kit picks up where it stops, adding a Ø 19 mm shaft and a run of professional bushings that reaches Ø 35mm. If you have been turning away big-axle wheels because the cones in the base kit will not fill the bore, this is the part that fixes it. Read the next paragraph before you order, because it is the thing that catches people out. This is an upgrade, not a starting point The kit will not work on its own. Part 8-21120012, the Motorcycle Universal Kit, has to be on the machine first — this set adds to it rather than replacing it. That is stated plainly in the manufacturer's own fitment note and it is worth repeating here in bold type, because the two products look interchangeable in a catalogue listing and they are not. If your balancer has never had motorcycle tooling on it, you need both. The reasoning is straightforward once you see the parts. The base kit supplies the dragging unit that fixes to the balancer flange, the small-bore cones and the wall panel. This kit supplies a second shaft, its own ring nuts, spacers and the larger bushings. Without the base kit there is nothing to drive the wheel; without this kit the base set runs out of range partway up the hub sizes. Where the extra range actually earns its money The bushing run here is Ø 22, 25, 25.4, 26, 28, 30, 32, and 35mm. Two things stand out in that list. The first is how closely spaced it is — there is no jump where a technician has to pick the nearest size and hope. The second is 25.4, which is one inch expressed in metric, and its presence is a quiet signal that the set is meant to cover cruiser and custom hubs built to imperial dimensions rather than just European metric ones. Getting the right bushing matters more on a motorcycle wheel than most people expect. A bike wheel is light, so the imbalance being measured is small — and a bushing a size under the bore lets the wheel sit fractionally off centre, which the machine then measures and reports as imbalance. The technician chases weights around a rim that was never out of balance. Filling the bore properly removes that whole failure mode, which is why a close-spaced bushing set is worth more in daily use than any feature you can see from across the workshop. Two ways to clamp The kit includes both a manual ring nut and a Ø 19 mm Quickfix ring nut, and the pair is deliberate. The manual nut threads down conventionally: slow, controlled, and the right choice for an expensive wheel you would rather handle carefully. The Quickfix pushes on and locks, which changes the economics of a busy day — when six wheels are queued on the floor, the seconds saved on every mount and dismount are the difference between finishing at five and finishing at six. Spacers are supplied with the set so the wheel stands off the flange correctly and runs clear. It is unglamorous hardware, and it is the hardware that stops a rim face touching something it should not. The wall panel, again Like the base kit, this one comes with a wall-mounted panel. A set of eight bushings in similar-looking sizes is exactly the kind of thing that ends up in three different drawers within a month, and the moment a shop cannot find one bushing, an entire class of wheel becomes un-balanceable until a replacement arrives. Mounted on the wall in order, a missing piece announces itself the moment you walk past instead of at the moment you need it. Will it fit your balancer? Corghi lists fitment for the EM9250/80, EM9550, EM9580 Touch and EM9980C, and the base motorcycle kit must already be fitted. If your machine is not on that list, do not order on the strength of the shaft size alone — send us your model and serial number and we will confirm it, because the locking arrangement has to match as well as the bore. One more distinction worth being clear about: this kit and the monolever kit are different products that both quote 19 mm. This one is for conventional wheels with an axle running through the hub, in the larger bore sizes. The monolever kit is for single-sided swingarm wheels that mount on a hub with no through-axle at all. If you service both, you need both — they do not substitute for one another. Perfect For Shops already running the base motorcycle kit that keep hitting the top of its bore range. This is the least disruptive fix for that problem: no machine, no floor space, one box. Cruiser and custom specialists, where the wide, heavy hubs and imperial dimensions sit exactly in the range this kit adds. Adventure and touring dealerships, whose wheels tend to the larger end of the hub sizes. General tyre shops taking motorcycle work seriously enough to want the whole hub range covered rather than the easy half of it.

For balancer tooling that is the norm — the approvals that matter usually sit with the machine, not with the adapters bolted to it. If your insurer, a fleet policy or a local requirement asks for documentation on shop equipment accessories, raise it with us before ordering and we will ask the manufacturer what exists rather than let it become a problem after delivery. Shipping and delivery Ships freight within the lower 48 states. Plan for someone to be present to take the delivery in, or elect to pick the shipment up from the carrier terminal instead. Deliveries to a residential address carry a fee. The freight cost is quoted live at checkout for your own address rather than printed here, because carrier pricing moves and a figure typed into a description would be wrong within months. Check the shipment over before signing for it, and write any damage on the bill of lading at the time — a clean signature is very hard to walk back once the truck has gone. Warranty The manufacturer's warranty applies. The term is not repeated on this page because it is not stated in the product data we hold, and a number we cannot verify is not worth printing — ask and we will send you the current document, and the downloads section on this page carries the warranty file where one is published. If a part does fail, start the claim before you take anything apart. Disassembly before assessment is the most reliable way to lose a claim that would otherwise have been paid.
