Direct answer: XSH-0017 is a clamp-on handlebar switch. Green horn button, red headlight button, left and right turn signal slider, five colour-coded wires on a 95 cm loom, 22 mm bar clamp, IP54 housing. It sold 4,300 units in the last twelve months through our own retail storefronts. At $3.60 a unit that works out to roughly $15,000 of retail sales, which is not much money. In units it is a part that never sits still.

Where the 4,300 figure comes from

We publish our own retail sell-through so a buyer can weigh a part against something other than a supplier's opinion. That is the point of this series.

The number is our direct-to-consumer volume, twelve months, one SKU. It does not include wholesale orders, distributor shipments or OEM runs. Those are larger and we cannot document them the same way, so they stay out of the count.

4,300 units is about 12 a day. That is the figure worth carrying into your planning, not the dollar amount.

Why a $3.60 switch sells steadily while $40 parts sit on the shelf

Switches are failure parts. Every motorcycle on the road has one clamped to the left bar, and it lives in the worst spot on the bike: direct sun, rain, road grit, and a thumb pressing it every few minutes.

Two things follow from that. The part fails on a schedule that has nothing to do with the model year, so demand is steady instead of seasonal. And it is cheap enough that nobody repairs it. A rider with a sticky horn button buys a new switch, fits it in twenty minutes and moves on.

That combination is what makes it a stock item rather than a feature. It is not going to carry your margin. It is going to be the line on the order that a workshop actually needs, and the reason they come back for the parts that do carry margin.

Two buttons and one slider, and the wire count proves it

The housing carries three controls. The green button on the left is the horn. The red button next to it is the headlight. The thumb slider on the right switches the indicators left and right.

The housing is rated IP54: dust protected, and safe against water splashing from any direction. That covers the realistic life of a left bar, which is rain, road spray and a hose at service time. It does not cover jets or immersion.

Five wires, four functions plus a feed. That ratio is not a coincidence, and it is the fastest way to check any switch before you buy it: count the wires, then count the functions you need. A switch with a high and low beam position needs six wires. This one has five, so the headlight is on or off, nothing in between.

The 22 mm clamp is the whole fitment story

A split ring closed by one bolt. Nothing about the fitment depends on the motorcycle's make, model or year. It depends on the bar diameter, and that is 22 mm.

7/8 inch is 22.2 mm, which covers most commuter bikes, small-displacement standards, scooters with a round bar, and most dirt and dual-sport machines. It does not cover the 1-1/8 inch tapered bars on current motocross and enduro bikes, and it does not cover the 1 inch bars on cruisers. If a customer rides one of those, this is the wrong part and no amount of clamping will fix it.

That is also why one SKU covers so many models. You are not buying a switch for a CB125 or a YBR or a KLX. You are buying a 22 mm switch, and the bike list is a side effect.

Five wires, five colours, one table

Wire	Function
Yellow	Main feed, 12 V in
White	Horn
Red	Headlight
Brown	Left turn signal
Green	Right turn signal

One feed, four switched outputs. The switch carries the current for each circuit directly, which is fine for a 35 W bulb drawing about 3 A and fine for an LED headlight drawing less. If a customer fits a 100 W bulb, the contacts will heat up and the switch will not last. Put a relay in that circuit.

It is a positive-side switch: it feeds 12 V out to each circuit. Most Japanese and Chinese machines are wired that way and it drops straight in. A bike that switches the ground side needs the wiring adapted, and that is workshop work rather than a plug-and-play swap.

The leads end in bare copper, not a moulded plug. That is deliberate. There is no standard connector across the thousands of models this fits, so you crimp or solder to whatever the bike already uses. Budget the labour for it, and buy the right bullet terminals before the first job.

Why 95 cm of copper matters more than it sounds

The loom leaves the back of the housing, so it tucks under the bar instead of looping in front of the grips. From the left bar to the headlight bucket and back into the main harness is usually 60 to 80 cm on a standard bike. 95 cm leaves slack for a bar swap, a riser, or a routing that avoids the steering lock.

The listing specifies full copper conductors. That matters more on a switch than on almost any other part, because the whole assembly flexes every time the bars turn. Copper tolerates that. Copper-clad aluminium work-hardens and breaks where the loom leaves the housing, usually within a season, and usually on a customer's bike rather than in your stock room.

What 100 pieces actually costs you to move

The spec sheet gives 0.1 kg per unit and a 10 x 8 x 10 cm individual box. A 100-piece carton is therefore about 10 kg and roughly 0.1 m³.

That is small enough to add to a lighting or body order without changing the freight calculation. It is also small enough that you can hold depth without tying up capital: 100 pieces is a shelf, not a pallet.

The unit ships in its own printed box, so a dealer can put it on a hook and sell it as it arrives. Custom logo, custom box and custom artwork are all available, but the setup only makes sense at 3,000 pieces and up. Below that the standard box is the better deal, and your own label on the shelf does the branding.

Four checks before you commit to a carton

Measure the bar. 22 mm or 7/8 inch only. Tapered 1-1/8 inch bars and 1 inch cruiser bars are out.

Count the functions. Horn, headlight on or off, left, right. If a customer needs high and low beam from the bar, this is the wrong part and they need the six-wire version.

Plan the termination. Bare leads, no plug. Crimping is part of the job, and a bad crimp on the main feed will look like a faulty switch.

It is IP54, not IP67. Splash and dust, not jets and not immersion. Tell customers to keep the pressure washer off the switch. Water driven past the buttons at 100 bar comes out as a corroded contact two months later, and the seal was never rated for that.

Questions dealers ask us

Will it fit a specific bike? Measure the bar first. If it reads 22 mm, check how many functions the original switch has. Two buttons and an indicator slider, and this is a direct replacement. Anything with a high and low beam position is not.

Is the red button a kill switch? No, it is the headlight. On most Japanese bikes the red button on the right bar is the kill switch, so tell your customers before they fit it, or you will get a call saying the bike will not start.

Can I have my own logo on it? Yes. Logo, box and artwork. The tooling and print setup make it worthwhile at 3,000 pieces and above, which is a distributor conversation rather than a first order.

What is the minimum, and how fast? 100 pieces on this listing. In-stock orders leave our warehouse in one to three business days; a made-to-order run takes longer, and the product page carries the current lead time. Mixed cartons with lighting and body parts are fine, which is usually how this part gets ordered.

Where to go next

The part is here: XSH-0017 universal motorcycle handlebar switch, with the spec sheet and the current price.

If you are building a stock order around it, the category index groups every range we manufacture, and the lighting and electrical range is where most of the volume sits. Send the part numbers and your target quantity through the contact form and we will quote the whole carton rather than the single line.
