Description
Bridgestone built the Battlax BT46R as a direct successor to the BT45, and in the 120/90-17 rear fitment it lands on some of the most popular vintage sport-touring platforms still being ridden hard today.
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 120/90-17 with a 64V load/speed rating, built as a tubeless rear tire
The 64V speed and load rating on this 120/90-17 tubeless casing covers everything from relaxed touring miles to a spirited backroad pace, and the bias-ply construction keeps the ride feel consistent with what the bike was designed around. Check rim width before mounting for the correct profile.
