Upgrade To Irresistible Pulling Power

POSTED: 22/10/2020

There are four stages along the path to optimising the performance of your Harley-Davidson, beginning with upgrades that will also enhance its iconic look and sound.

Our experienced workshop teams can help you choose the best options for your riding style and specific model.

Enquire online, visit our stores, or call Riders in Bridgwater (01278 457652) or Bristol (0117 958 8777) for a no-obligation chat.

Read on for an overview of the four stages and the performance improvements you can look forward to from each one.


Stage I from £999
Intake + Exhaust + Tuning

However big your pulling power ambitions may be, the 5-10% power increase from Stage I is where all Screamin’ Eagle® performance upgrade journeys begin. Choose from a range of high-flow air filters and slip-on mufflers to deliver that extra horsepower and make your bike look and sound even more irresistible.

Once the Stage I foundation is in place, build on it with Stage II or jump straight ahead to Stage III or IV.


Stage II from £849
Cam Upgrade + Tuning

The quest for optimum air flow continues in Stage II with a camshaft upgrade suited to your style of riding.

For an increase in power of up to 15% in the low to mid RPM range, choose the Torque Kit option. Alternatively, go for the Power Kit option if up to 25% more power at higher revs is what will get your heart racing.


Stage III from £2,499
Includes Stage II + Big Bore Cylinders + Pistons

With air flow taken care of, the next step is to increase your engine’s displacement and compression for more torque across the whole power band and a 15-25% improvement in the mid-range.


Stage IV from £3,499
Includes Stage III + Cylinder Heads + Throttle Body

Maximising displacement, compression and flow, Stage IV puts the icing on the cake. The ultimate Screamin’ Eagle® performance upgrade delivers a 20-30% increase in power right up to the red line without sacrificing mid-range torque.


Riders of Bridgwater Limited is an Appointed Representative of Automotive Compliance Ltd, who is authorised and regulated by the Financial Conduct Authority (FCA No 497010). Automotive Compliance Ltd’s permissions as a Principal Firm allows Riders of Bridgwater Limited to act as a credit broker, not as a lender, for the introduction to a limited number of lenders.

We can introduce you to a selected panel of lenders, which includes manufacturer lenders linked directly to the franchises that we represent. An introduction to a lender does not amount to independent financial advice and we act as their agent for this introduction. Our approach is to introduce you first to the manufacturer lender linked directly to the particular franchise you are purchasing your vehicle from, who are usually able to offer the best available package for you, taking into account both interest rates and other contributions. If they are unable to make you an offer of finance, we then seek to introduce you to whichever of the other lenders on our panel is able to make the next best offer of finance for you. Our aim is to secure the best deal you are eligible for from our panel of lenders. Lenders may pay a fixed commission to us for introducing you to them, calculated by reference to the vehicle model or amount you borrow. Different lenders may pay different commissions for such introductions, and manufacturer lenders linked directly to the franchises that we represent may also provide preferential rates to us for the funding of our vehicle stock and also provide financial support for our training and marketing. But any such amounts they and other lenders pay us will not affect the amounts you pay under your finance agreement, all of which are set by the lender concerned. If you ask us what the amount of commission is, we will tell you in good time before the Finance agreement is executed. All finance applications are subject to status, terms and conditions apply, UK residents only, 18’s or over. Guarantees may be required.
