Life was much different 70 years ago. An average male worker earned just £9 per week, a gallon of petrol cost 4 shillings and 6 pence (equal to 22p today) and a loaf of bread was just 4 pence. At the time, BSA, Triumph and Norton were all releasing new motorcycles, today’s cherished classics.

SRM pressure plates

Ariel Huntmaster engine with new SRM Timing Side Bush



Although most customers opt for the Needle Roller Bearing Conversion, we are still able to replicate the original timing side bush as fitted originally.

The crankshaft journal is ground to remove wear, and an undersized (internal) timing side bush is fitted to the crankcase.

The bush is then bored to match the crankshaft diameter plus the clearance of 1 ½ to 2 thou.



Problems with heavy clutch action, cable resistance and cable routing on your BSA A65?

Our hydraulic clutch conversion provides a light clutch action and is maintenance-free for your convenience.

The conversion works by replacing the cable operated three ball clutch lifter with a hydraulic slave cylinder and pusher.

The kit consists of

  • SRM Clutch slave cylinder

  • Internal connection pipe

  • Adaptor for the hydraulic pipe

  • Clutch pushrod pusher

BSA Anniversary


This week marks the 111th anniversary since BSA started production of their first motorcycles: the 3.5HP models. Being new to the classic motorbike world, this was the perfect opportunity for me to look at the history of BSA and some of their motorbikes. So, with the help of our managing director Jon (a BSA enthusiast), several different books and the 1911 edition of The Motor Cycle magazine, I am writing this article for you to enjoy.

Engineer interviews - Mark

Having been part of the SRM team for just over two months now, I have gained some basic knowledge of classic motorbikes and the rebuild and restoration processes. I've come to see that the staff and engineers I work with are highly skilled in what they do and just as passionate about their bikes as our customers. Therefore, to better understand their passion, I asked them about their favourite bikes and the roots of their interest in the beloved classic motorbikes. This week I spoke to Mark, our parts specialist, about his experience with classic motorbikes.
