Do you think your bike deserves every single accessory that could give it more style and protection? We have a brake oil cap for your KTM Adventure 390 from our premium brand Legundary Custom. It is recommended to change the brake fluid of your bike every year. Otherwise, you might face brake failure on heavy braking. So it is always better to keep the brake fluid safe for a safer ride. Our brake oil cap can act as a guard for the reservoir as well as give a facelift for your bike. The product featured here is made with stainless steel.
