DescriptionThe whole story▼

A genuine upgrade for everyday riding and weekend track days alike, the BST Diamond Tek carbon rear wheel brings measurable weight savings and sharper handling to the Aprilia RSV4, RR, and 1100 Factory (model years 2021–2026) — without asking you to compromise on safety certifications or long-term durability.

Key Features

  • Ultralight construction at just 4.0 kg (8.82 lbs), reducing unsprung mass for noticeably quicker acceleration and more responsive handling on both road and track.
  • Pre-preg carbon fibre construction paired with a 6082 T6 aluminium hub for an optimal balance of rigidity, vibration damping, and corrosion resistance.
  • DOT E and JWL certified — fully approved for road and circuit use, giving you confidence whether commuting or pushing lap times.
  • Impressive load ratings: 445 kg radial load, 711 Nm cornering load, and 995 Nm torsional load, engineered to handle the full demands of Aprilia's flagship superbike platform.
  • BST Ultra-High-Speed valve included — a 90-degree aluminium valve with cap, ready for high-speed tyre pressure management.
  • Supplied in the OEM fitment size as standard; alternative sizes available on request.
  • Backed by a 2-year factory warranty, underlining BST's confidence in the quality of every wheel they produce.

Built for Road Riders Who Demand More

Not every performance upgrade belongs exclusively on the track. The Diamond Tek rear wheel is engineered to deliver a tangible improvement in the riding experience during daily use — smoother corner entry, a more planted feel under hard braking, and a liveliness through direction changes that the standard cast wheel simply cannot replicate. The weight reduction has a compounding effect: less rotating mass means the engine works less hard to accelerate, tyres heat up more evenly, and suspension components respond more accurately to road surface inputs. For riders who want the most from their RSV4 without stripping it back to a track-only machine, this wheel hits the sweet spot.

Materials and Construction

BST uses aerospace-grade pre-preg carbon fibre, where each layer is precisely laid up and cured under controlled heat and pressure to guarantee consistent fibre alignment and resin content. The result is a wheel with no weak spots and no excess material — every gram serves a structural purpose. The aluminium hub is machined from 6082 T6 billet, chosen for its superior strength-to-weight ratio and compatibility with standard Aprilia axle hardware. Bearing options include conventional steel bearings for everyday road use or ceramic bearings for riders seeking the lowest friction and longest service life at elevated temperatures.

Finish Options

The Diamond Tek is available in a range of finishes to suit the look of your RSV4: high-gloss clear coat to showcase the natural carbon weave, satin-matte finish for a more understated appearance, forged carbon finish for a distinctive textured aesthetic, or a selection of solid colours — blue, red, green, gold, silver, orange, and black ink — applied to the carbon structure for a bold, personalised result.
