been manufacturing it for nearly 15 years. There are a lot of cheap, crappy internal throttles out there, but we believe ours to be the best available. The assembly converts your carburetor or EFI to single cable action, but unless your cable is severely kinked the throttle will still snap shut when the grip is released. You can modify your existing throttle cable to work, but remember you will need an adjuster either at the lower end of the cable or mid-cable. Alternatively you can use our Throttle Cable Kit. The handlebar insert portion of the assembly measures 0.825" in diameter, which we have found to be the perfect size to fit in the bore of most 1" bars. This diameter can be turned down on a lathe if it needs to be reduced to fit, for example, 7/8" bars. On request we can supply the Internal Throttle Assembly with a 1" diameter handlebar insert (this is what we use when fabricating our 1.25" bars). The twist-sleeve measures 1.145" diameter, which is the same diameter as the Harley nylon throttle sleeve. This means that any grips that work with the HD throttle sleeve can be used with our assembly. We offer stock-style rubber grips and our knurled billet aluminum grips.


TCK Throttle cable kit, over-length, designed to work in any application


LTA Left Twist Assembly $40 $249


This is basically a reversed-spiral version of our Internal Throttle Assembly that can be used on the left side of the bars to operate a cable. What you use it for is your business, but we originally developed it to activate the clutch. The spiral is twice as steep as the throttle assembly to double the amount of leverage that is applied to the cable. We use it routinely on our bikes in combination with our ‘universal’ Twist Clutch Cable to activate the stock HD clutch or the Primo diaphragm clutch resulting in a smooth, light twisting operation at the grip – and super-clean bars! Our Twist Clutch will, of course, work with other clutches, but remember that the stronger your clutch springs the harder the grip


will be to twist. BEWARE OF CHEAP IMITATIONS! TCC Twist Clutch Cable for all HD ’86-up

The Hidden Switch System comprises one small, slim rubber strip of switches that will handle all of your switching needs. The individual buttons control turn-signals, horn and High/Low beam. Holding two buttons down simultaneously will activate your starter. The switch strip attaches by a single wire to a tiny module that can easily be hidden under your tank or seat.


We offer a variety of grips that are available WITH or WITHOUT a machined recess in the left grip to mount the Hidden Switch System.

The grips above have a left grip that fits a 1” bar and a right grip that fits over a stock HD nylon throttle sleeve or our internal throttle. Two left or two right grips can be supplied on request at no extra charge (e.g for twist-clutch application). Please note that if you are using a twist-clutch you cannot have the switches in the left grip as it is full of moving parts. In these cases we mount the switches directly into the bar itself

CFC Centrifugal Clutch assembly Add Add $150


$150 $699


Below about 1200 rpm the clutch is automatically disengaged. This makes riding a foot-clutch bike extremely easy. You do not need to touch the foot pedal to shift from neutral to first, or to pull away from a stop. You do not need to touch the foot pedal whilst coasting to a stop and shifting down through the gears. In fact, the only time you need to physically operate the clutch pedal is whilst accelerating up through the gears (as the rpm does not drop sufficiently between shifts). We can supply the centrifugal clutch assembly fitted to any of our belt drives, but it can also be used in many other applications, including closed primaries. Call for details.
