Description
The 120/80-18 Battlax BT46R gives classic sport and touring bikes a rear tire that has been re-engineered from the ground up rather than simply reissued under a new name.
The BT46R keeps the bias-ply construction that these older frames and suspensions were tuned around, but Bridgestone updated the compound and tread pattern so it grips better in the wet, wears more evenly, and does not feel vague at speed the way a lot of old-school rear tires can. It is a straightforward, no-drama replacement rather than a tire that asks the rider to relearn the bike.
Key specs and features:
- Bias-ply carcass construction matched to the original vintage sport and touring platforms it replaces
- Tubeless design on most sizes for simpler maintenance and easier repairs than older tube-type equivalents
- Successor to the long-running BT45, developed with a modern tread compound and profile
- Tuned tread pattern intended to improve wet and dry grip over the outgoing BT45 design
- Sidewall styling that keeps the classic look expected on a vintage-era machine
- Consistent, predictable steering response suited to relaxed sport and touring riding
- Sized 120/80-18 with a 62H load/speed rating, built as a tubeless rear tire
This 120/80-18 62H tubeless casing is a common rear fitment on classic sport-touring bikes, and running it alongside a fresh BT46 front keeps both ends of the bike working off the same modern compound. Verify rim width compatibility before mounting.
