The Kyosho OT251B Aluminum Roll Bar is a no-fuss upgrade for hobbyists wanting a tougher body mount. It is engineered for the Javelin and can be used with the Optima once the Javelin roll cage body is in place, boosting durability with minimal fuss.
This aluminium roll bar fits the Javelin roll cage body precisely, offering a tidy installation. When the Javelin roll cage is installed on an Optima chassis, the OT251B will work there too, making it handy for drivers who swap shells for different events.
Installing the OT251B is quick and intuitive. Its dimensions match Javelin mounting points, so you can bolt it on without custom mods. For Optima use, confirm the Javelin roll cage is correctly seated to ensure proper alignment.
