Welcome to Sumo Rubber!

We are home of quality rubber parts for classic Japanese motorcycles.


Who are we?

Sumo Rubber is a family company, founded by myself and my husband Jason.

We both have a strong customer service background, and we love motorcycles, especially old classic Yamaha and Enduro models.

When our boy was very little, our friend offered us an opportunity to open an online retail store selling his aftermarket Yamaha parts.  Despite having limited knowledge of motorcycle ins and outs, we embraced the challenge. Four years down the line our business have gone stronger and bigger. 

We have decided to part with the exclusivity of our friend's supply and venture our own way. We now have over 10 different suppliers, including a direct importer from Japan, and we have a growing range of exclusive parts.  We are also lining up certified factories abroad that will help us provide the much-needed quality alternative to the currently available aftermarket parts, as well as help us reproduce some of those rubber parts that have been missing for years.

Not only that, but we hope that by building great relationships with our customers, we can bring something different to the otherwise cold, technical world of online shopping for spare parts.


Why Sumo Rubber?

We chose the name Sumo as it represents both strength and challenge. We want to create a strong brand in the small niche market of aftermarket and obsolete parts.

The challenge for us is to compete with the growing number of “one-stop shops” that promise to supply all parts under the sun, regardless of quality and reliability. The word Rubber just came to us naturally, as most of our products are made from rubber material.

We understand that especially rubber parts have a limited durability and disintegrate over time. Unfortunately, old motorcycles are full of these small rubbers which bought individually, might seem cheap, but if all needing replacing, might cost a small fortune. So that is where we would like to come into play, offering either OEM parts or quality alternatives that will not break your bank.


Our product

Due to circumstances, we decided to concentrate firstly on Yamaha parts. But our vision is to expand to other Japanese brands too. We understand that the majority of our customers have more than one motorcycle in their garage. As such, it would be an advantage to offer as many perishable parts as possible from the same store.

There are also some rubber parts that are compatible between the various Japanese brands.

We continuously scan the current market for obsolete parts that are in demand or that are suggested to us by our customers. We keep a list of those in demand and slowly work through it, bringing you new high quality reproduction parts on a regular basis.

Quality control is also very important to us, and we encourage all our customers to give us a review or feedback.


Our values

As a family run business, we value loyalty, honesty and reliability. We want to build our business on positive experience and provide our customers with the best service possible. We have experienced first-hand the frustration a customer can face when buying from a shop that concentrates only on turnaround and sales, and we promised to ourselves that though we want Sumo Rubber to be profitable and successful, we don’t want to compromise our customer’s experience. As such, we will always aim to answer all enquiries to our best ability!


Our vision

Our business idea was inspired by our friend who, several decades ago, set off for a journey from the United Kingdom to India on an old Yamaha motorbike. A journey that started as a bet between brothers, ended up changing lives to thousands of people by setting up factories, charities (like JBF Scotland) and supporting local communities in India. We are grateful for the legacy, experience and attitude of our friend, who is an ongoing inspiration for us.

But as mentioned above, our business vision and goals are much bigger and that is why we decided to break away from the trading limitations and go our own separate way, creating our own range of products and brand.

We would like to expand our range of products to cover any rubber parts for not only Yamaha motorcycles but also jet skis, boats and snow mobiles that are obsolete or hard to obtain and there is still a demand for their parts on the market. We are also looking into diversifying to other brands such as Kawasaki and Suzuki.


Final words

We are hoping you will find our website easy to navigate, and we are looking forward to your feedback, suggestions and reviews.
