DescriptionThe whole story▼

Fitting a new clutch lever to an RSV4 RF is often the moment owners discover that the clutch has two separate adjustments. One is the reach, which decides where the lever rests in front of your fingers. The other is free play, the small slack before the clutch begins to disengage. They are easily confused, and getting either one wrong changes how the bike pulls away. The Accossato ESV004 is a CNC-machined aluminium clutch lever for the RSV4 RF of 2015 to 2019, with its own reach adjuster and three blade lengths.

Key Features

  • Clutch lever for the Aprilia RSV4 RF, 2015 to 2019
  • Installed at the original clutch mounting in place of the stock lever
  • Integrated reach adjuster near the pivot
  • Blades: short, standard (approximately 138 mm), long
  • Black hub with a blade in one of seven colours
  • Anodised aluminium, machined from the solid
  • No folding joint, one rigid piece
  • No German ABE documented; sold for track use

Construction and Material Quality

On the ESV004, everything adjustable lives in the black hub: the pivot bore and the reach adjuster sit there, while the coloured blade is simply a rigid arm that carries your pull. Accossato machines the whole lever from solid aluminium on CNC machines and anodises it, so the colour is part of the metal and the edges stay crisp. With no hinge anywhere along the blade, the only movement is the rotation around the pivot.

Reach and Free Play Are Two Settings

Reach is about your hand. It moves the resting position of the blade nearer to or further from the grip without changing how the clutch itself behaves. Free play is about the mechanism: a little slack at the start of the lever's travel ensures the clutch is fully engaged once you let go. On a cable-operated clutch, that slack is set at the cable adjuster, not at the lever. The two still interact, because bringing the blade closer to the grip leaves less lever travel for disengaging the clutch.

After fitting the ESV004 to your RSV4 RF, set the reach first, wearing your riding gloves, so the fingers meet the blade comfortably. Then check two things with the engine running: with the lever pulled to your fingers in gear, the bike should not creep forward, and with the lever released, a trace of free play should remain so the clutch cannot slip under load. The standard blade of about 138 mm is closest to the original; the long one, in blue, gold, green and orange, lightens the pull, and the short one, in blue, gold, green, orange and silver, suits two-finger use.

Fitment and Compatibility

The ESV004 fits the RSV4 RF of 2015 to 2019 at the original clutch mounting. Accossato's catalogue entry for this model reaches back further than the bike itself; because the RF was introduced for 2015, this product follows its real production years. The same lever is named for other RSV4 versions and for the RS 660. For the front brake of the RSV4 RF, the matching Accossato part is the EDF011, likewise offered for 2015 to 2019.

Road Approval

A German ABE is not on record for this clutch lever, and we sell it accordingly for track use.
