Evolve your Harley-Davidson® horsepower and energise your torque!
The colder months are here and for many of us, that means no more riding until it gets a bit warmer. But whilst you're not on the bike, why not upgrade your ride in time for the new riding season? Utilising our top-of-the-range performance-enhancing stage upgrades, you'll be turning heads wherever you go.
From Stage One, you’ll feel up to a 10% increase in performance throughout the entire RPM range. Then as you go up the Stages, your motorcycles overall performance, sound and feel will continue to evolve up to 50% further.
Scroll down to find out how we can evolve your beast...
STAGE I
Enhance your Harley-Davidson® motorcycle with our Stage 1 performance package. Stage 1 upgrades are hugely recognised in the community and will add substantial value to your ride.
With Stage 1 you’ll receive an instant boost in performance. We customise a brand-new Air Cleaner kit and Exhaust System to your riding and style preference, creating less restriction for escaping gases and more overall engine airflow. We hold a variety of different brands, giving you full freedom when enhancing your engine's performance, look and style.

STAGE II
Take your Harley-Davidson® up a notch with our Stage 2 performance package. Stage 2 upgrades again add value to your ride and up to 25% in performance. Stage 2 is where we tailor your ride to you, giving you the choice of Torque Cam or Power Cam.
Our Torque Kit is perfect for riders looking for an instant acceleration boost, increasing your throttle response and acceleration.
Our Power Kit enhances your ride with a new essence of speed, perfect for an adrenaline-pumping burst of speed.

STAGE III
Pump up the volume of your Harley-Davidson® with our Stage 3 performance package. Stage 3 is where the magic happens, accomplished by larger cylinders and matching pistons.
The increase in displacement allows your engine to intake more air and fuel – a higher compression piston then squeezes the air and fuel into a better-combusted source, pushing you further. With an increase of up to 35% performance, the upgrade will deliver instant passing power and on-tap acceleration.

STAGE IV
The unmatched level of Harley-Davidson® performance upgrade, is our Stage 4 performance package. Stage 4 adds higher-flowing CNC ported cylinder heads and a larger bore throttle body. This increases the velocity and feeds a larger amount of air and fuel into the engine – maximising power on larger displacement engines. In addition to combining ported cylinder heads and larger throttle body - in combination with cylinders, matching pistons, and proper cam - this achieves up to a 50% performance increase.

Laguna Motorcycles Limited (which include multiple trading names: Laguna Motorcycles, Laguna Performance Centre, Laguna Triumph, Maidstone Honda, Maidstone Harley-Davidson® and Kent Motorcycles 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 allow Laguna Motorcycles Limited (which include multiple trading names: Laguna Motorcycles, Laguna Performance Centre, Laguna Triumph, Maidstone Honda, Maidstone Harley-Davidson® and Kent Motorcycles to act as a credit broker, not a lender, for the introduction to a limited number of lenders, and to act as an agent on behalf of the insurer for insurance distribution activities only.
We are a credit broker and not a lender. We can introduce you to a lender on our panel, which includes lenders of vehicle manufacturers. We have commercial arrangements with lenders and credit brokers which are likely to influence who we introduce you to. We are not an independent financial adviser and don’t give you any advice or recommendations. It is your choice whether you enter into any finance agreement. Our approach is to introduce you first to the manufacturer lender linked to the franchise offering you the vehicle. They will usually offer the best available package for you, taking into account both interest rates and other contributions (but we do not guarantee they do). If they are unable to offer finance, we then seek to introduce you to someone else on our panel. We will usually receive a commission for your introduction. This will be either a fixed fee, or a fixed percentage of the amount that you borrow. This may be linked to the vehicle model you choose. Lenders of vehicle manufacturers 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. Before we propose you to a potential lender, we will tell you of the likely amount of commission we will receive and seek your consent to receiving this commission. The exact amount of commission will be confirmed before you sign your finance agreement.
All finance applications are subject to status, terms and conditions apply, UK residents only, 18s or over.
