Sportster – Dyna – Softail – Road King – Touring – V-Rod – Street Glide – CVO

Tailored Harley-Davidson Power Packages from SAC Raging Bull

SAC Raging Bull is the country’s leading aftermarket vehicle tuners, but as you may or may not know, we have been actively involved in successfully and reliably extracting extra horsepower from Harley-Davidson motorcycles for the past few years.

Steve Fischer, our company’s founder and the man who started his engineering career on motorcycles more than three decades ago, is the driving force behind this independent division situated in Vanderbijlpark in the Vaal Triangle. Although we service the whole South African market.

SAC Raging Bull is just not any outlet either, this state of the art facility that is equipped with the latest tools and equipment, right down to a new generation loading and inertia dyno, compares to the best Harley-Davidson workshops you can find anywhere in South Africa.

Harley Davidson Stage 1 - 4

The Basic Stage 1 upgrade consists of fitting a performance air cleaner, we have a choice of three or four different styles and they can be tailored to your individual styling and performance needs. A low-pressure performance exhaust system or slip-ons that carry the Vance & Hines or Screaming Eagle name is next on the menu. If necessary, the catalytic converters can be removed or optimised on selected models.

Stage 2 sees the cylinder heads gas flowed to perfection along with the option to fit bigger valves and an enlarged throttle body, from 46 mm to 50 mm.

The final piece of this puzzle is the choice of what camshafts you want to run. They offer from mild to wild, but remember the part about knowing what power you want. Fischer and our team will help you here and advise you accordingly. This sees your 73 kW increase to anywhere from 80 to 88 kW, depending on your camshaft option.

The ultimate is the Full House Stage 3 option that sees the pistons and barrels being changed and your 96 Cube increased to 103 Cube (1700 cc) for a power output that goes beyond 88 kW to anywhere just above 100 kW. This is enough to transform any Harley into one exciting and very rideable machine!

Obviously, power upgrade options exist for the other engines in the range, but take the time to read through the rest of our site, as this is discussed in massive detail to make sure that you are making the right decision when it comes to all your Harley-Davidson needs. Who knows, by contacting SAC Raging Bull on – 016 981 7199 and making use of our services, you just might save yourself a fortune by injecting new life into an older machine you were thinking of selling instead of buying a new bike.

What do you use your Harley Davidson bike mostly for, riding fast and alone on weekends or leisurely touring with your partner? You might even just want to know that your Harley is running as good as it can and is using as little fuel as possible. Having a Harley that is making wild horsepower at top is not going to be pleasant to ride when fully loaded; a bike that is too noisy is going to be no fun on the open road either.

Just as an upgrade to increase midrange torque is not going to satisfy a weekend speed junky who enjoys blasting along the open road with his buddies. So before you opt for one of our legendary Stage 1, 2 or 3 Full House Harley upgrades, be sure you know what it is you want when it comes to the performance of your Harley-Davidson. And for the sake of comparison and to better explain our menu of upgrade options and power gains expected, it is worth noting that the most popular engine in the Harley range is the 96 Cube (1600 cc) as it covers over 75% of all the models on the road today, and it is the one we will use from here on out for illustration purposes.
