Authentic reproductions of the original WR gas tanks as used on the 1946-1952 production race bikes of the same name. The narrow shape and omission of the speedo assembly achieve that much sought after racy look.

Front Runners or Skinnies are used on drag cars as front tires but since their size so nicely fits rear wheels of motorcycles it’s a possible choice for your classic style speed project. They fit most stock fenders and feature a simple, circumferential grooves thread pattern.

This reproduction of the classic Harley-Davidson oil tanks covers the years 1952 to 1966 and fits K-models as well as early Sportster models. Unlike later tanks, it has no welded mounting bracket and is designed for models without electric start.

These quickturn throttle grips generate the same stroke at a rotation of 150 degrees as the original grips at 180 degrees. The scope of delivery includes handlebar grip sleeve, control cable plunger, cable and hardware.

The Cannonball StealthStarter system converts your classic kickstart-only Harley-Davidson to electric start. After installation you just push the button or turn the key to fire up your classic Big Twin.
The Cannonball SSK electric start system bolts between kicker cover and transmission case. The stock kick starter can be retained. Due to the system’s low profile, only ¾” (19 mm) wide construction the overall appearance of your motorcycle will remain virtually unchanged. Primary drive, primary housing and oil tank will stay untouched.
Installation is fairly easy and straightforward. The kit includes everything needed for the conversion except for the extended throwout bearing, battery, wires and starter button/switch.
If the bike is still equipped with an early stock 6 V electrical system, you will have to convert this to 12 V. Depending on the configuration some other options are available separately.
Since the kicker cover moves 19 mm to the right the following modifications may be necessary:
A stock 2-1 exhaust system will have to be routed slightly outward to compensate for the offset of the kicker cover. , A longer clutch release lever will be necessary on rod actuated configurations like Moustraps or Footclutch. A longer lever can be ordered seperately if needed., A extended throwout bearing must be ordered seperately for your type of clutch pushrod since the stock pushrod will be 19 mm too short.,
A longer brake crossover shaft will be necessary on all bikes using the original mechanical rear brake in conjunction with the original 2-1 or similar exhaust. A longer crossover shaft can be ordered separately if needed. ,
Original rear fenders need to be slightly dented for starter motor clearance. Alternatively, an aluminum “Dent” can be ordered separately. In this case the fender needs to be cut out to allow the “dent” to be mounted with the original lower fender mount bolt and the two oil tank/battery tray bolts.

Gravel, rocks and roadkill – here’s an awesome tire knowing no fear. Whistle into town, come back home across the fields Steve McQueen style. Do some hooligan racing among friends on the neighborhood dirt track. Or what about that camping trip to that place where the road ends you’ve been postponing all those years? The Bates Baja tires can handle it.
Here’s a family of scrambler tires right on the tracks of the legendary Goodyear Grasshopper, capable of doing it all: ample grip on the road with a tread pattern that will get you out of the deepest ruts off the road.
The Bates tires Baja are the product of Bates’ long experience on diverse gravel, dirt and mud pistas, highways and Autobahns on several continents. For continuous quality control we use them on our daily riders.
We’re having this classic square section tire produced to the highest technical standards. The design matches perfectly most vintage, bobber and chopper style bikes. The available wheel sizes can be freely combined. Your next vintage scrambler project should be awesome.
It’ll give that extra twist to that off-the-wall vintage rigid project of yours, or use it to give a whole new attitude to your custom bobber or 70th style swingarm.
The tires are certified for speeds up to 190 kph.

Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in their horseshoe oil tanks will highly appreciate this fact. On the other hand, owners of classic bikes do like the looks of their original energy store and the corresponding cover and mounts. With a Bates BattBoy Battery Box you can have the best of both worlds, because what looks like a period type HM5 6V accumulator on the outside can house a safe, modern battery within. Just hook it with two eyelet wires to the terminals on the bottom of the lid and you are all set. Perfect for 6 to 12 volts electrical system conversions, too. When using suitable Antigravity versions you even have some storage room left for a few small spare parts, safety vest, Cuban cigars, etc. Ain't this one heck of a cool solution for an old problem?

Detailed reproduction of the DeLuxe solo seat from model years 1955–1980, manufactured according to original specifications for classic Harley-Davidson Big Twin models and authentic restoration projects. The seat comes fully assembled, including the “Royalite” rubber skirt that provides the characteristic original appearance. Two chrome-plated, diamond-shaped trim pieces on the sides and several chrome-plated rectangular trim pieces along the back of the skirt complete the classic look, making this seat a high-quality, period-correct solution for vintage and old-school bikes.

This special fuel valve by Prism Supply fits directly into the 3/4"-18 tank bung originally used on Harley-Davidson Knucklehead and Panhead fuel tanks – ideal for vintage bikes, old-school restorations, and custom projects. It features a 5/16" diameter hose barb and an integrated fuel filter, ensuring clean and reliable fuel delivery. For a snug, leak-proof fit, we recommend using fuel lines with a 1/4" inner diameter.
Fuel flow is controlled by rotating the lower cylindrical operating piece with the two grooves, allowing precise on/off operation without twisting the attached fuel line. The original crossover line can still be used, while the internal through-tank linkage is completely eliminated.
The kit includes two brass sealing washers and a cap for the top of the tank. Available in brass or stainless steel.

That placing sheepskins on the relatively hard horse saddles significantly increased riding comfort was already known to the cowboys. So it didn’t take long until sheepskins were also fitted to the Troxel and Mesinger seats of the pioneer motorcycles of the 1910s and 1920s. The Wrecking Crew came to greatly appreciate this during the Cannonball Race in the USA, where riding times of 8–10 hours a day on the 1915 H-D Model J were quite normal. It’s truly amazing what a difference a piece of sheepskin can make. It’s super comfortable, insulates against engine heat, and keeps you warm when temperatures drop. Even a rain shower isn’t a problem, as sheepskins naturally absorb very little moisture. Finally, such a cover is also an excellent way to protect an aged original seat that you no longer want to expose to the elements.
The reproductions of these seat covers by The Cyclery are made in Norway from Wellington sheepskins, precisely following the original patterns. The edges feature a canvas piping with sturdy metal eyelets and a drawstring, allowing the cover to be quickly installed and securely fastened. And if the bike has to spend the night outdoors, it can just as easily be removed in no time.
The Cyclery sheepskin seat covers embody living tradition: functional, authentic, and made for all who value comfort and a classic look. Available in natural white and natural black.

This air cleaner trim is an accurate reproduction of the ribbed insert for use with the iconic oval AMF-era air cleaners.

Designed to look good on all kinds of cafe racers, choppers and bobbers. The nostalgic appearance hides a full SMD-LED circuit board which works as running light, brake light and number plate illumination through a window on the underside. The sturdy housing mounts directly with two studs to all flat surfaces or with an optional bracket.

Finally available again! Oil line fittings for classic style oil tanks and pumps thru 1964. They feature the correct 9/16”-24 HD thread and press fittings for 5/16” ID rubber oil hose. Thus you can fabricate custom rubber oil lines in no time. Class A quality.

Damn! Rolled past the bar again!
If you are looking for significantly more stopping power, you should consider replacing your classic drum brake system with a disc brake.
After extensive 3D simulations on the computer and countless test kilometers on any terrain, we can now rightly claim that this brake meets our high requirements.
This kit developed by Cannonball converts Harley-Davidson models with Big Twin, Servi-car or WLC Springer forks from drum brake to disc brake.
Each kit includes a: dual piston caliper with pads, , caliper bracket, , 10” disc rotor, , brake anchor, , wheel hub adapter, and all small parts necessary for final assembly. ,
Brake lines and handlebar master cylinder are not included and must be ordered separately.
Kits that are delivered without axle reuse the OEM axle (please see article details).

This saddlebag set in the original “Black Magic” design is made of Royalite – a durable ABS injection-molded material developed by Uni Royal Rubber Co. in the early 1950s. Each bag consists of an upper and lower section. The upper parts feature integrated locks for added security.
The spacious lower sections provide ample storage and are accented with a chrome band around the top edge. Round rivets in authentic factory style complete the vintage look. These saddlebags are ideal for Harley-Davidson restorations and period-correct custom projects.

A strictly bolt-on solution for the two common problems where to mount the passenger pegs and the lower end of the solo seat springs on rigid frames. No welding, no drilling, no clamps. This combo bracket easily mounts with the upper bolts of the rear fender brackets and supports the springs at the correct angle and holds the passenger pegs in a convenient position. Fits stock 1936-1957 or similar Big Twin rigid frames.

As faithful, docile sidevalves, the 750 cc Harley-Davidson models have a small power shortfall. To correct it, the rule is: nothing replaces cubic inches… except more cubic inches!
With Truett & Osborne Stroker flywheels, the stroke increases from 3-13/16” to a full 4-1/2”, giving 876 cc instead of 742 cc (54 cuin instead of 45cuin).
Special Stroker pistons are required and are also available. Installation is not straightforward: the flywheels must be balanced to the piston and connecting rod weights, and the engine cases and cylinders must be machined.
We therefore recommend consulting an experienced workshop.
The selection includes:
flywheels for stock 45” crank pin and connecting rods, flywheels for racing purposes which work with stronger 1957-84 Sportster crankpins and connecting rods,

Quite some S&S engines have been delivered with classic style ribbed cam covers using modern allen screws with 1/4”-20 Thread in counterbore holes. It is not possible to change to classic OEM Style sloted screws - even if they do have the right thread for the aftermarket case - since those would require a cam cover with countersink holes. This kit consists of 12 hybrid screws to fit counterbore holes but having the classic head of OEM countersunk screws.

These minimalist hydraulic brake pedals with pre-assembled mounting plates bolt directly to Big Twin frames and are ideal for chopper conversions. Designed for Big Twins 1936-1969 but can be used on later models with minor spacing applied. Oil-impregnated bushing and the CNC-machined shaft and spool ensure perfect function and accuracy of fit. Includes push rod for Lockheed Wagner Style master cylinders.

The Dyna S ignition from Dynatek fits all Harley-Davidson cam covers on Big Twins (1970–1999) and Sportsters (1971–2003). It can serve as an electronic replacement for the original breaker points and condenser through 1978 or as a substitute for faulty control modules on Late Shovel and Evolution engines. Models originally equipped with electronic ignition require an additional advance mechanism.
The Dyna S switches much more precisely than mechanical points. The advance timing adjustment is purely mechanical and, once correctly set, requires no maintenance.
Available as Dual Fire (both cylinders fire simultaneously, as in the original) or Single Fire (each cylinder fires separately at the end of its compression stroke).
