DescriptionThe whole story▼

Small hands and fixed levers are a bad combination on a ZX-4 RR. LighTech builds the KLEV142J as a kit, so one order covers both bar ends of the ZX-4 RR. LighTech lists it for the ZX-4 RR.

Key Features

  • 450 g
  • Listed for the Kawasaki ZX-4 RR
  • Both levers fold — they give way instead of snapping at the perch
  • LighTech part number KLEV142J
  • One order covers both bar ends of the ZX-4 RR
  • 100 % Made in Italy, tricolour logo on the blade

Both Sides at Once

Magnesium and aluminium are not chosen for the look of them. Where the original blades transmit a crash into the master cylinder, the KLEV142J folds out of the way. The three models — J, K and H — differ in finish and geometry, not in construction.

Mounting It

The KLEV142J goes on with the ZX-4 RR on its stand, engine cold. Work the levers through their full travel before you trust them on the ZX-4 RR. Check the pivots again after the first ride.

Fitment

LighTech catalogues the KLEV142J for the ZX-4 RR (2026). The KLEV142J uses the original pivot bolts and the original perches of the ZX-4 RR. Have KLEV142J and the model year to hand and the question is settled in one message.

Before You Order

Before ordering the KLEV142J, note what is in the box. KLEV142J is the complete lever set for the ZX-4 RR: brake side and clutch side in the same box. Keep the part number KLEV142J — a later single-side order is then unambiguous.

What You Get

LighTech ships the KLEV142J as a pair, brake and clutch together. Keep the reference for a later single-lever order.

Road Approval

According to LighTech, the range meets the requirements of the applicable road regulations. No type-approval certificate accompanies the KLEV142J, whatever the manufacturer states. If the ZX-4 RR carries a plate, ask your inspection body before fitting — practice differs by region.
