Description
For 17-inch rear wheels on vintage-era standards and sport-tourers, the 120/80-17 Battlax BT46R replaces the outgoing BT45 with a bias-ply carcass tuned for how these bikes are actually ridden now.
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 120/80-17 with a 61H load/speed rating, built as a tubeless rear tire
Carrying a 61H rating and tubeless construction, this 120/80-17 BT46R suits lighter and mid-weight vintage machines that see a mix of commuting and weekend riding. Pair with a matching BT46 front and confirm rim width before installation for the intended handling balance.
