Oval – working from 110mm Ø is sized 98mm wide and 122mm High and can come in sizes from 250mm to 450mm Long. (This is our slimmest design, for inverted under-seat exhausts, or for customers/Racers who need the slimmest streamlined spacers to ride through).

(This is our Premium shaped design. (Designed back in 2002′ our company was the first in the UK to produce this exclusive shape, have a look around and see how many UK companies have copied us!!).

All our Road Legal exhausts, come with a removable Road Legal Baffle / Decibel Killer + BSAU ( British Road-Legal ) markings.

Once the removable baffle is unbolted the exhaust is then classed as a RACE Exhaust and is not road legal.

All our RACE exhausts do not come with a removable Road Legal Baffle / Decibel Killer + do not have any BSAU ( British Road-Legal ) markings.

Extra Info

Our Exhausts are manufactured to give maximum power without the need to alter the fueling but, if you have an aftermarket air filter and/or a de-cat, then having the bikes fueling looked at will always compliment the engine’s performance and efficiency.

To Make sure that you are shopping for the correct Model exhaust here is some information about this model.

The Yamaha YZF-R125 is a sport motorcycle designed by Yamaha and manufactured by MBK Industrie since 2008. It currently has 3 generations.

First generation: (2008 – 2013)
In 2008, the bike initially came available as a four-stroke replacement for the TZR125. Entering the thin market of small displacement 4-stroke sportbikes, it quickly gained traction and became a popular choice for young riders.

Second generation: (2014 -2018)
In 2014, Yamaha unveiled a facelifted version of the bike with a slightly tweaked fairing set, an upside-down front fork, and a full LCD dashboard.
It launched without ABS, but it became an option for 2015 and comes as standard equipment on all bikes since 2017. This may cause minor differences in weight and electrical or other specifications.
In 2016, the LCD instrument received a minor revision, in which the segment arrangement for various gauges has been slightly modified, including a horizontal tacho instead of a vertical one.

Third generation: (2019 – on)
The 2019 revision brings some major changes: New rear swingarm, tweaked frame, rebuilt cowling, a new engine with Variable Valve Actuation (VVA), and many other minor modifications add up to a brand new construction. With this release, Yamaha brings it’s R-series superbikes aesthetically more or less in line with each other.
