Sport Touring Road Battlax BT46 The Battlax BT46 is set to replace the iconic BT45. Since its introduction 22 years ago, the BT45 has been the go-to tyre for touring. Now, Bridgestone has upgraded this design with modern technology. The Battlax BT46 features an inverted V-shape in the front tread pattern, which tackles working forces on the tyre, reduces irregular wear and gives the rider incredible feedback for superior handling. The rear tyre is enhanced with a newly adapted silica single compound to maximise performance, grip and wear. Wet performance has been upgraded from the BT45, with no impact on the predecessor’s well known dry handling performance and wear resistance. The BT46 is also compatible with UM application: meaning it is approved for mounting on tube type rims (certain sizes only).
