Servicing at House of Thunder
At House of Thunder, servicing is more than routine maintenance - it is a specialist discipline. As a dedicated Harley-Davidson specialist, our servicing is engineered around the real-world demands of Harley riders, from daily road use to long-distance touring and performance riding.
All work is carried out in strict accordance with manufacturer service procedures and recommended schedules, ensuring reliability, longevity, and full mechanical integrity. Our workshop processes are the result of years of specialist training and hands-on experience, allowing our technicians to deliver consistent, high-quality outcomes across all Harley-Davidson models from Evolution and above.
In addition to our Harley expertise, House of Thunder is proud to operate as an authorised main dealer for multiple manufacturers, providing dealer-standard servicing with specialist-level care:

While manufacturer requirements and service needs can vary significantly, our experienced technicians apply the same structured workshop procedures, technical diligence, and attention to detail across all brands we support.
For motorcycles outside our core dealer franchises, the best approach is to contact us directly to discuss your specific requirements. This allows us to confirm service scope, parts availability, and manufacturer guidelines, ensuring your motorcycle receives the correct level of care and compliance.
If you ride it, we are happy to advise on how best to service it.
Tyre Supply and Fitting - House of Thunder Motorcycles
House of Thunder offers a professional motorcycle tyre supply and fitting service, tailored to the performance, safety, and handling requirements of each individual bike. We specialise in Harley-Davidson models and our core main-dealer brands, while remaining fully open to bookings from riders of other motorcycle makes and styles.
We supply the latest-generation tyres, correctly sized and date-coded to ensure optimal performance, longevity, and compliance. Motorcycle tyres are not interchangeable commodities - each fitment is engineered with specific load ratings, speed ratings, and construction types to suit different weights, riding styles, and applications. Selecting the correct tyre is critical to stability, braking, and overall ride quality.
Our experienced team understands these technical differences and will provide clear, informed advice to ensure your motorcycle is fitted with tyres that meet the exact requirements of your machine and how you ride it. From cruiser to performance applications, you can rely on House of Thunder for correct specification, professional fitting, and confidence on the road.
Diagnostic Testing Services
At House of Thunder Harley Specialist, we provide comprehensive diagnostic testing services using manufacturer-grade equipment and specialist software to ensure accurate fault identification and effective repair decisions.
For Harley-Davidson motorcycles, we utilise advanced diagnostic platforms such as TechnoResearch, enabling full system interrogation across all control modules. This allows us to accurately diagnose component failures, analyse live operating data, perform calibrations, and resolve model-specific issues in line with factory standards rather than relying on generic fault-finding methods.
Our capabilities extend beyond fault diagnosis. We can reprogram and code ECUs and BCMs, carry out ABS diagnostic procedures, and complete system initialisation and reset functions where required. We are also able to unlock Harley-Davidson motorcycles that have been immobilised due to lost key fobs or forgotten PIN codes, restoring access and functionality safely and correctly.
In addition, we perform diagnostic testing to full manufacturer standards and warranty procedures for our main dealer brands, including QJ Motor, Morbidelli, and BSA Motorcycles. This ensures all testing, reporting, and verification meet factory requirements for warranty claims, technical investigations, and complex electrical or electronic faults.
Our diagnostic process is precise, data-driven, and fully manufacturer-compliant - giving customers confidence that issues are correctly identified.
Batteries - Supply and Fitment
At House of Thunder Harley-Davidson Specialist, we supply and professionally fit motorcycle batteries tailored specifically to your Harley-Davidson. We have extensive hands-on experience testing and evaluating a wide range of battery types, from factory-fit lead-acid units through to modern lithium and hybrid technologies.
We understand that the correct battery choice is critical and depends on more than just model year. Engine capacity, compression, electrical load, and performance modifications all play a role. Based on real-world testing and application knowledge, we can recommend the most suitable battery for your bike to ensure reliable starting, optimal performance, and long-term durability.
To minimise downtime, we regularly stock a select range of batteries covering many popular models across the Harley-Davidson lineup. If your application requires something more specialised, we can source the correct unit quickly and ensure proper installation.
Whether you are replacing a failed battery or upgrading to support engine or electrical modifications, you can rely on expert advice and quality fitment.
