2023 Mutt Fat Sabbath 125 | Used Bike for Sale UK

This is a 2023 Mutt Fat Sabbath 125, priced at £1,595 ONO. The bike has approximately 9,500 miles on the clock and is still being ridden daily, so that figure will rise slightly. It is being sold as the current owner is completing their MOD 2 and moving on to a bigger machine.

Key Features

Condition and History

The bike is an honest, used example rather than a showroom piece. The seller states it has been ridden as a daily, so it carries the usual marks and weathering you would expect, with the exhaust area specifically mentioned as showing signs of this. It is not being sold as pristine.

Mechanically, the bike is described as running and riding well and has been reliable for the seller. The mileage is approximately 9,500 and will rise slightly as it remains in use.

The history is solid on paper. A fresh service was carried out at 8,700 miles by DB Custom Works, which included a new rear brake disc and pads along with a general health check. Since then, the bike has also had a new clutch cable fitted and upgraded adjustable CNC brake and clutch levers. The MOT is valid until the 15th of February 2027, which gives plenty of peace of mind for the next owner.

The number of previous owners is not specified in the seller’s details. Ask the seller for further details on the number of previous owners if this is important to you.

Why Consider This Vehicle

This Mutt Fat Sabbath 125 makes a strong case for itself as a first big step into motorcycling. The long MOT until February 2027 and the recent service by DB Custom Works—including new rear brake components—mean the essentials have been seen to recently, which is exactly what you want on a used 125. The seller is also being straightforward about the cosmetic condition, describing it as a used daily rather than trying to pass it off as mint, which usually means fewer surprises when you turn up to view it.

About the Mutt Fat Sabbath 125

The Mutt Fat Sabbath 125 is part of the modern retro scene that has become very popular in the UK, particularly among riders looking for something with a bit of character rather than a generic Japanese commuter. The Mutt brand is known for producing small-capacity motorcycles styled like classic flat trackers, bobbers, and scramblers, but with modern running gear underneath.

The Fat Sabbath, with its chunky stance and stripped-back look, is generally known for being a head-turner. Bikes in this class tend to attract attention at bike meets and in town, far more than your average 125. They are typically seen as a great choice for CBT riders who want to learn the ropes on something that looks and feels like a “proper” motorcycle, rather than a scooter or a more conventional learner bike. The riding position is usually upright and confidence-inspiring, which suits new riders building their road sense.

In the UK market, these bikes are often bought new or nearly new by riders who then move up to a full licence, meaning they frequently appear on the second-hand market with relatively low mileage. That pattern is evident here. The 125cc engine class is ideal for learning, being cheap to run and insure, and the Mutt’s simple, air-cooled nature generally makes them straightforward for basic maintenance and ownership.

What to Check Before Buying

If you are considering this Mutt Fat Sabbath 125, there are a few practical things worth doing before you commit.

The seller has been upfront about the cosmetic condition, mentioning weathering particularly around the exhaust. That is fairly typical for a bike used through a British winter, and it is worth having a close look at that area in person. Check the condition of the exhaust system itself — surface rust or discolouration is common, but you want to make sure there are no holes or blowing from the pipe. Also have a look at the condition of the chain and sprockets. These are consumable items on any bike, and a quick visual check will tell you if there is life left in them or if you will need to budget for replacement soon.

Ask the seller about the service history beyond the recent one. The service at 8,700 miles by DB Custom Works is documented, but it is useful to know if there are any earlier receipts or records. Check the tyres for tread depth and any signs of cracking, even if the bike has low miles, age and weather can take a toll on rubber.

The MOT is valid until February 2027, which is a genuine plus, but it is still worth running a free MOT history check online using the registration number. This will show you the mileage recorded at previous tests and any advisories that were noted. It is a quick way to verify the bike’s story matches the paperwork.

Always do an HPI check on a used bike to confirm there is no outstanding finance or insurance write-off history against it. This is standard practice in the UK and costs very little compared to the peace of mind it offers.

Finally, check the V5C logbook is present and that the seller’s details match up. With a bike of this style and age, it is likely still on its original number plate, so just make sure everything is consistent before handing over any money.
