Although the CST brand isn’t well-known in Europe, the company actually also produces Maxxis tyres, its sister brand that we are all familiar with.

As a matter of fact, CST is the world’s largest manufacturer of tyres for two-wheelers and with more than 20 000 employees throughout its 3 factories in Taiwan and China, CST tyres benefit from expert, award-winning R&D and product development, ensuring the very best performance.

The CM733 features deep knobbies that will bite the dust for the best possible cornering grip and stopping power all the while featuring a grippy compound that sticks to dry and rocky terrains.

In addition, its central tread blocks efficiently release mud for a constant grip in the harshest conditions.
