Why Bonamici Racing Rearsets Are the Best Track Upgrade for Aprilia RS660 Riders

CLICK HERE to upgrade your Aprilia RS660 rearsets

The Aprilia RS660 is one of the best “real-world fast” sportbikes ever built. It’s light, sharp, and confidence-inspiring, which is exactly why so many owners end up doing track days. But once you start pushing the RS660 at lean angle and braking deeper, the stock rider triangle becomes the limiting factor. You need more precision, better boot support, improved body positioning, and the ability to fine-tune your ergonomics to match your riding style.

That’s where Bonamici Racing rearsets become the smart move for track-focused RS660 riders. The Bonamici adjustable rearsets (part number A006) are designed and manufactured in Italy with the kind of details that matter when lap times and consistency are the goal: CNC-machined billet construction, high-quality bearings for smooth controls, multiple adjustment positions, and support for both standard and reverse shift patterns.

What track riders actually need from rearsets (and why it matters on the RS660)

On track, rearsets aren’t a “looks upgrade.” They’re a control upgrade. The benefits show up in four key areas:

1. Ground clearance and lean angle confidence
   As you increase corner speed, you’ll eventually touch pegs or feel the bike’s limits through hard parts. Rearsets can increase ground clearance and help you maintain your line without unwanted contact mid-corner. That confidence is worth time, but more importantly, it keeps your inputs calm and consistent when you’re at the edge of traction.

2. Body position and bike control
   The RS660 responds best when the rider can lock in with the lower body and keep weight off the bars. Adjustable rearsets let you place your feet where they naturally support hanging off, loading the outside peg, and keeping your torso stable under braking and direction changes.

3. Shift and brake feel that stays consistent session after session
   Sloppy linkage feel, friction, and vague lever travel add mental noise. At speed, that noise becomes missed shifts, inconsistent downshifts, and uncertainty at turn-in. Premium rearsets reduce friction and improve the precision you feel at your boot.

4. Ergonomic adjustability for YOU
   No two track riders are built the same. Peg position that works for one rider can feel cramped or unstable for another. Adjustable rearsets let you tune peg height and rearward position to match your inseam, flexibility, riding style, and even your track’s cornering profile.

Bonamici Racing RS660 rearsets: the details that make them the best option

Bonamici doesn’t just “move the pegs back.” The A006 rearsets are engineered around the things that track riders notice immediately.

CNC-machined billet aluminum strength
Bonamici rearsets are CNC-machined from high-strength aluminum alloys. That matters on track because rearsets take real loads: hard braking, aggressive peg weighting, repeated shifts, and the occasional off-track moment. Billet + precision machining gives you a stiff, accurate platform that holds alignment and feels solid under pressure.

Double ball bearings for ultra-smooth control feel
One of the biggest performance differences with the Bonamici setup is the use of double ball bearings in the linkage to reduce friction and keep the shift and brake action smooth. When your controls move freely and consistently, your brain spends less energy “interpreting” the bike and more energy riding your line.

Return spring on the brake lever
Track riding is a game of repeatability. A brake lever return spring helps keep the rear brake lever feel consistent and predictable, especially as things heat up and your sessions stack.

6-position adjustability (dial in your track stance)
Bonamici provides multiple adjustment positions so you can set your peg height and reach where it best supports your riding. That means you can run a more aggressive, track-focused position for ground clearance and leverage, or a slightly less extreme setup if you’re balancing comfort with control.

High-grip, race-inspired footpegs
On track, boot support is everything. Bonamici uses race-inspired pegs with a high grip level so your feet stay planted when you’re hanging off, weighting the outside peg, or catching a quick upshift at full lean.

Standard shift or reverse (GP) shift capability
As riders get faster, many prefer reverse shift (GP shift) for upshifts while leaned over. Bonamici rearsets support both standard and reverse shift configuration, so you can keep your current pattern or switch when your pace and preference evolve.

Non-folding (fixed) pegs and toe pegs for track precision
For track use, fixed pegs are a feature, not a downside. They feel direct and solid, and they’re less likely to introduce movement at the worst time. Bonamici supplies these rearsets as a complete left and right kit with fixed footpegs and toe pegs as standard equipment.

Anodized finish for mechanical and chemical resistance
Track bikes get abused: brake fluid, chain lube, cleaners, heat cycles, and general wear. The anodized finish is designed for improved resistance to mechanical wear and chemical agents, keeping your rearsets looking good and functioning well for the long haul.

Heelguards included, and upgrades available
Bonamici rearsets come standard with black aluminum heelguards, and there are optional add-ons (like carbon heel plates/guards and folding upgrades) if you’re building a more personalized setup. That’s a big deal for track riders who want to “lock in” their boot and keep their foot position consistent lap after lap.

Brake light function retained (street-to-track friendly)
If your RS660 still sees street miles between track days, it’s nice when a performance upgrade doesn’t create a bunch of wiring headaches. These rearsets retain rear brake light functionality using stock components, making the transition from street riding to track weekends easier.

Fitment: built for the RS660 family (and beyond)
The Bonamici A006 rearsets are vehicle-specific and listed for Aprilia RS 660 model years 2020 through 2026, including RS 660 Extrema and RS 660 Factory variants, and they also cross-fit the Tuono 660 lineup across multiple years. If you own an RS660 that’s becoming more track-focused over time, this is the kind of “buy once, cry once” upgrade you won’t outgrow.

How to set up your Bonamici rearsets for track days (practical guidance)

If you want a baseline track setup:

1. Start with the peg slightly higher and slightly rearward than stock to gain clearance and improve leverage.

2. Set your shift lever so you can upshift without lifting your whole foot off the peg. You want a quick toe movement, not a full ankle gymnastics routine.

3. Set your brake pedal height so you can cover it when needed, but not so high that you drag rear brake mid-corner.

4. After your first session, make only one change at a time (peg position OR lever height), then ride again. Consistency wins.

Who should choose Bonamici rearsets for the RS660?

Bonamici Racing rearsets are the best choice if you:

• do track days and want a more aggressive, controlled riding position

• need more ground clearance and stability at lean angle

• want smoother, more precise shift/brake feel through bearings and quality linkage design

• plan to switch to reverse (GP) shift now or later

• want a premium, Italy-made rearset kit that’s built for performance, not just appearance

The Aprilia RS660 is capable of serious pace, and the fastest way to unlock that capability isn’t always horsepower. It’s control. Bonamici Racing adjustable rearsets give you the adjustability to fit the bike to your body, the grip to stay locked in when you’re hanging off, and the precision to make braking and shifting feel clean and repeatable. For RS660 riders who take their bikes to the track, this is one of the most meaningful upgrades you can make.
