DescriptionThe whole story▼
Three point nine kilograms off a 143 kg motorcycle. That is nearly three per cent of the whole machine, from one component, and it is one of the largest weight savings in this entire catalogue in proportional terms.
Key Features
- 1.8 kg against the standard 5.7 kg: 3.9 kg and 68.4 per cent less
- 2.1 Nm more at 4,100 rpm — low in the range, where a 286 cc single works
- Carbon fibre construction
- Twenty minutes to fit
- No road approval — circuit use only
The Peak Figures Do Not Move
Peak power goes from 29.0 PS to 29.1, and peak torque stays at 27.2 Nm. Neither changes in any meaningful way.
The gains Akrapovic publishes — 1.3 PS and 2.1 Nm — are measured at 4,200 and 4,100 rpm respectively, in the middle of the range. The curve is lifted there and the ceiling is untouched. That is the honest description, and it is a more useful result on a small single than a higher peak would be.
Where Honda Put the Weight
5.7 kg of standard silencer on a 286 cc motorcycle is a remarkable figure — heavier than the exhaust on some 900 cc bikes in this catalogue. Honda met Euro 4 on a cheap single the way manufacturers usually do, with a large steel box.
Removing more than two thirds of it is the single most effective change available to a CB300R owner.
Twenty Minutes
A clamp, two bolts and a spring. The CB300R's silencer is mounted high on the right with nothing over it, and the job needs no lift and no special tools.
Carbon on a Small Honda
The CB300R was Honda's attempt at a premium small naked — LED lighting, an IMU-free but well-sorted chassis, and a price above its class. A carbon silencer suits that positioning in a way a plain steel one would not.
Three Model Years Only
Honda sold the CB300R in this specification from 2018 to 2020 before a Euro 5 update changed the exhaust. Check the year in the registration document — the bikes look identical from the outside.
Twenty Minutes and a Socket Set
A clamp, two bolts and a spring, with the silencer mounted high on the right where nothing covers it. This is a job an owner does in a garage without a lift, and the standard part goes back on just as quickly when the bike is sold.
A Single, Not a Twin
The CB300R runs a 286 cc single, which is why the torque gain sits at 4,100 rpm rather than up near a twin's power peak. Singles make their useful pull low and run out of breath early, and an exhaust that helps them does it down there or not at all.
