Cafe Racer Kit: What You Need, and the Parts That Fit
A cafe racer kit is the handful of parts that change the look and riding position: a seat and rear hoop, low bars, bar-end mirrors, a small headlight and a compact tail light. Bike-specific kits fit one model; universal parts fit many, but only if you match three measurements first: your fork tube diameter, your bar diameter and your headlight size.

What a cafe racer kit includes
| Part | What it does | The size you must match |
|---|---|---|
| Seat and hoop | Solo seat and the loop that closes off a shortened rear frame | Frame rail width and usable length |
| Clip-ons or clubmans | Lower, forward bars for the tucked-in stance | Fork tube diameter (clip-ons) or handlebar clamp size (clubmans) |
| Bar-end mirrors | Mirrors that sit in the bar ends once the stock mirrors go | Bar diameter (7/8in, 22mm, on most Japanese and European bikes; many Harleys use 1in) and the bar-end insert |
| Headlight | Smaller or cleaner round light | Headlight diameter (5.75in or 7in) and mounting type |
| Tail light and indicators | Compact lighting for a short tail | Mounting holes, wiring and your local lighting rules |
| Rearsets | Move pegs, brake pedal and gear lever back | Usually bike-specific |
The seat is the biggest single change and has its own guide: cafe racer seats and how to fit one.
Clip-ons: buy them by fork tube size
Clip-ons clamp around the fork tubes, so the one number that matters is your fork tube diameter where they will sit. Measure it with calipers. The same clip-on design is often sold in several sizes, so pick the listing for your size:
| Fork tube | Clip-ons | Per the listing | |
|---|---|---|---|
| 35mm | venveal 35mm clip-ons | Listing confirms a 35mm clamp, 40mm clamp height and 300mm bars. Its title names many older Honda and Suzuki models, but check that your own fork tube is 35mm before ordering. | Check price → |
| 35mm (with riser) | HYEPIVOT 35mm clip-ons with 1in riser | Same 35mm clamp with a 1 inch riser, so the bars sit higher for a slightly more upright position. | Check price → |
| 37mm | HIYOYO 37mm clip-ons | Bars angled 10 degrees down, 300mm long, 40mm clamp height. | Check price → |
| 39mm | HIYOYO 39mm clip-ons | Same design in a 39mm clamp. | Check price → |
| 41mm | HIYOYO 41mm clip-ons | Same design in a 41mm clamp. | Check price → |
All five take 7/8 inch (22mm) bars. Check that your grips and controls are also 7/8 inch: many Harleys use 1 inch bars and controls. Before ordering, check there is enough bare fork tube below the top yoke (or above it) to mount them, and that the bars clear the tank at full lock. The CB750 guide lists what owners report for that bike, but measure your own.
The other parts worth buying
AnXin 7/8in Clubman Bars
Clubman bars are one-piece bars that mount in the stock handlebar clamps (if your bike uses 7/8 inch bars) and sit lower and further forward, giving much of the cafe look without fitting clip-ons. The listing says they are steel, 7/8 inch, and that modification may be required.
FENRIR Round Bar-End Mirrors (pair)
Round mirrors that mount in the ends of 7/8 inch bars, a common choice once clip-ons or clubmans go on. The listing warns that some bikes need extra adapters, says to fully tighten the three screws, and suggests blue threadlocker against vibration.
FATECIM 5.75in LED Headlight with Visor
A small round headlight suits the stripped front end of a cafe racer. This one has a visor, a 10mm bottom mounting bolt and four wires (the listing does not say which is which, so check the wiring before fitting). The listing does not state DOT approval, so check your local lighting rules.
LEDUR 7in LED Headlight with Bucket and Brackets
If your bike already has a 7 inch light, this replaces it with a complete unit: bucket, fork clamp brackets (the listing gives 32 to 42mm fork tubes in one place and 32 to 40mm in another), a standard H4 plug and built-in amber turn signals. The listing says it is DOT approved and explains how to deal with non-standard H4 wiring and indicator flicker.
MFC PRO LED Tail Light with Plate Bracket
Short tails leave little room for lights, so an all-in-one unit with tail, brake, number-plate light and indicators on one metal plate bracket is a tidy answer. The listing gives the wire colours for each function. It does not state DOT approval, so check local rules.
TADAFA Seat Hoop with LED Strip (230mm)
A seat hoop with an LED strip built into the tube for brake, tail and turn signals, so the lights disappear into the tail. This listing is the 230mm-wide version (it also names 215, 195 and 175mm widths), it is bare steel that may show a little rust, and the listing says polishing, cutting and welding may be needed to fit it.
Rearsets: why we did not pick a universal set
Real rearsets move the footpegs, the brake pedal and the gear lever back together, with new linkages, and they bolt to mounting points that differ from bike to bike. That is why good sets are almost always made for one model. Some universal listings sold as "rearsets" ship only a pair of footpegs, which leaves your controls where they were. If you want rearsets, look for a set made for your exact model and year, and check it includes the brake and shift linkage.
Building a Sportster cafe racer kit
TCT-MOTORPARTS Sportster Headlight Fairing
A painted black ABS headlight cowl with mounting hardware. Its listing says it fits 1973-on Sportster and FX/XL-series models (the seller writes "Dyna FX/XL") with 39mm narrow-glide forks and a 5 3/4 inch headlight, so check both on your bike first. It is built around a 5 3/4 inch headlight cutout; neither listing says whether the FATECIM light on this page, which has its own visor, fits inside it, so confirm before buying both.
Sportster fork sizes, headlights and controls changed over the years, so start with our Sportster donor guide to see which era you have and what it needs.
Fitting order and wiring
Fit the parts in the order that avoids doing anything twice: get the bike running, charging and stopping first, then bars and controls, then lights and wiring, then the seat and hoop, and paint last. The build sequence explains why. Smaller lights and LED indicators often need new connectors and an LED-compatible flasher relay or load resistors, and moving the seat can mean finding a new home for the battery; see wiring basics. Budget the whole job with the cost breakdown.
Cafe racer kit: FAQ
What is in a cafe racer kit?
Usually the parts that change the look and riding position: a seat (often with a rear hoop), clip-on or clubman bars, bar-end mirrors, a smaller headlight, a compact tail light and sometimes rearsets. Bike-specific kits from specialist shops bundle these to fit one model. On Amazon you mostly buy them as separate universal parts, which means checking each size yourself.
Are universal cafe racer kits worth it?
They can be, if you measure first. Universal parts are widely available and cover many bikes, but each one has a size that must match yours: fork tube diameter for clip-ons, bar diameter for mirrors and grips, headlight size and mounting, and frame width for a seat hoop. Bike-specific kits remove most of that guesswork.
What size clip-ons do I need?
Clip-ons clamp to the fork tubes, so you need your fork tube diameter where the clip-on will sit, usually just above or just below the top yoke. Measure it with calipers rather than trusting a forum; clip-ons are sold in sizes from the low 30s to the low 50s in millimetres, with 33, 35, 37, 39 and 41mm among the common ones. Check too that there is enough bare tube above or below the yoke to mount them.
Do I need rearsets with clip-ons?
Not always, but low bars with stock footpegs can leave you stretched out and cramped at the same time. Proper rearsets move the pegs, brake pedal and gear lever back together, so they are usually bike-specific. Be careful with cheap universal listings: some sold as rearsets are only a pair of footpegs with no linkage.
Is there a cafe racer kit for the Harley Sportster?
There are Sportster-specific parts, such as headlight fairings made for the Sportster front end, alongside universal seats, bars and lights. Fork tube size and headlight size vary by Sportster year and model, so measure before ordering. See our Sportster donor guide for the model differences.
Do I need to change the wiring for a cafe racer kit?
Often, yes. A smaller headlight, LED tail light and LED indicators can need new connectors, an LED-compatible flasher relay (or load resistors) and a new home for the battery and electrics if the seat changes. Plan the wiring before the bodywork; our wiring basics guide covers the essentials.
