Hit the road with the all new Roadsmith HDST-R conversion kit, and experience the trike-riding difference. With a longer wheelbase, generous additional storage, award winning body design, independent suspension, disc brakes, optional electric reverse, and Roadsmith steering kit, you may never want to return home!
The Roadsmith HDST-R conversion is designed for the 1988 and newer Harley-Davidson Softail models. That's the Heritage Softail, Fatboy and Night Trains.
The Roadsmith features our independent rear suspension with a 5" longer wheelbase. That, in simple terms, means it rides like no other trike on the market.
The smooth ride of the Roadsmith HDT is primarily due to our innovative suspension system that offers a ride like no other trike. The Trike Shop was the first to offer independent suspension for trike conversions over 20 years ago. The cynics said it would never work. They're eating those words today. Talk to anyone who has actually ridden an independent rear suspension and a solid axle system trike for a period of time and ask them which one rode better. They won't deny independent rear suspension rides nicer and corners awesome. IRS is the way manufacturers of cars, SUV's and ATV's have been and are going. Trikes are built with a purpose "Touring in Comfort".
The multi-point mount of the chassis to the bike frame actually strengthens the bikes frame as well dissipates the added stress of a trike. We attach to existing mounting points on the frame like the upper shock mounts and the swingarm mounting area. A feature of the trailing arm type independent suspension is the fact that there are very few moving parts. There are literally only two pivot points on each trailing arm. This eliminates any adjustments or maintenance requirements. There are more complicated ways to design a suspension, but why?
We have designed this kit with automotive parts that are easily accessible, should you happen to need service on the road. The rear brakes are large 11" dual disc. The Constant Velocity (CV) joints and brakes are VW Beetle application. These heavy duty parts for a light duty application have proven to be dependable for extremely long.
Bolts solidly to the bikes frame via the inside of the fender strut mounts and the swingarm pivot area of the bikes frame. This design actually strengthens the bike frame, thereby reducing the torsional flex that a trike puts on a frame.
Our new adjustable length swing-arm that now carries our differential has a unique adjustment system that has a central cam adjuster, similar to an axle adjuster. When the hex-bar is turned, the cams evenly push back the differential to tighten the trike belt. Just tighten the nuts up on the machined and slotted swing arms and you’re done. The differential housing simply has a set of spider gears in it, and is filled permanently with gear lube.
It's that kind of detail and engineering
we've put into the design of this
conversion. We don't want to leave
you hanging with some special parts
or tools required for you to drive your
trike for many years to come.
The stabilizer bar also known as a sway bar is a flexible link between the two trailing arms. The bar uses the torsion effect to always try to keep the trike righted or sitting square to the ground. The beauty of the stabilizer bar is the fact that when one wheel hits a bump, the bar can flex quickly to absorb the movement then return. This is the same technology used in almost every vehicle today. Just think if you had “no lean”. This means your trike is always perfectly square to the ground. In effect, if you go over a 2” bump with your right wheel the trike rocks up 2”. With Independent Suspension, just that wheel goes up. The antiquated solid axle system is only made today because it’s cheaper and easier. Technology has improved a lot in the short history of trike conversions but some are too stuck in their ways. We offer only the most innovative designs to our customers.
We increase the wheelbase of this bike by 5". This puts the rear wheels back behind the passengers’ seat area rather than sitting right on top of the wheels. Any vehicle that has a longer wheelbase will have a smoother ride, and trikes have proven no different.
Large disc brakes more than handle the stopping of this trike. Remember trikes stop faster and easier than bikes. With more tire contact area and much better stability, braking a trike is not the white knuckled balancing act that a bike can be. The wheel bearings, calipers and rotors are all right from a high production automobile application known as the VW Beetle.
Like all of our constructed drive train,
we use everyday parts off the shelf for
The axles are custom made for our conversion kits but the constant velocity (CV) joints are standard automotive applications such as VW and Porsche. We use automotive type parts for all of our drive train because it’s designed for a much heavier load, meaning these parts will probably last forever in this light duty application. Again using off the shelf parts for your convenience.
The Alloy wheels that come with our conversion kits are clear-coated aluminum rim that has a similar look and finish to the bike front rim. They are a 16x7”, 5x4 1/2, positive 35mm offset size that fits many automotive applications. We also offer a Chrome plated option.
Dual exhaust is required for a Softail. The HDST-R needs a new set of cross-over exhaust pipe extensions and a set of new throaty mufflers. You can purchase the crossover set through us in addition to the base kit if you wish.
The large storage compartment comes completely carpeted to both protect and store your riding gear. The trunk (4.5 cubic feet) has about 50 percent more capacity than the stock saddlebags. This gives you a larger space to fit larger objects into. The large trunk door opening also allows for easier packing or loading. This convenient trunk will fit all of your gear securely away from the elements.
The slick body design incorporates the look and feel of the original motorcycle. It also features and industry first, single handed trunk opening operation. We feel the trike conversion body should melt seamlessly into the original body parts. The body is constructed of heavy-duty fiberglass. It is then painted with urethane paint, flat sanded, and buffed to a mirror finish to ensure a perfect paint match both in color and finish. The mounting system for the body ensures a rock solid attachment and no exposed mounting hardware. The added foot room for the passenger is another beneficial feature of a longer wheelbase.
With any touring machine a trailer hitch is a familiar sight. When riding a trike, a trailer is not a danger like it is on a bike. The back of a trike will never feel like there’s a trailer behind it. We include a 1 1/4” receiver for a trailer hitch neatly tucked under the body. It is incorporated into the rear body support and is welded directly into the strongest part of our frame. This is not an option or add-on, it’s built right in. It is another one of the innovative ideas built into the design of our trike kit.
The Trike Shop has an unparalleled history of customer service and satisfaction and we put it in writing, with the best warranty in the market. Your trike comes with a full 3 year or 1,000,000 mile warranty on the entire trike kit. We can offer this because we know with over 14 years of producing this type of conversion kit, we do it right the first time.

An option that we offer and highly recommend is our 6 degree raked triple trees. We push the front axle ahead to reduce the trail in the front end. Remember when we call these rake kits, what we really are changing is the trail. We are changing the trail from about 6.69" to 4". By doing this, it acts like you have wider handlebars in the sense that it gives you more mechanical leverage to turn the trike.
This handy new option
cornering performance, and also helps reduce unwanted body roll that can come from heavy loading or riding with a passenger.
A unique and cool option we have developed is our Electric Reverse System. This electric motor is not just a starter motor, but rather an extremely high torque 12V motor that goes through a gear reduction to produce huge torque. To operate the reverse, simply lift the lever
the electric motor's gear directly into the front of the belt's sprocket. One you've engaged the motor simply push and hold the bike's horn button down to back you up. When done, put the engagement lever back down and the horn button will be a horn button again.There is a safety built in so if you put the bike in gear while the lever
is up, the horn sounds! You'll
probably only do that once.
You can have matching front and rear wheels by ordering our custom wheel package. This billet front wheel comes in a highly polished finish and matching polished brake rotors. The front rim is machined to match our chrome 16" wheels pictured below.

If your front tire has a white wall,
you should have matching tires
in the rear, right? We offer them
with fat 1 1/2" white walls, thin
3/8" white walls, or for the
2009's a 3/16" thin white wall.
The tires are specially made
