DescriptionThe whole story▼

Acid Yellow puts Leatt's ultra-light race pant into a colour you will not lose in a busy pit lane. The Moto 5.5 I.K.S is a form-fitting race pant cut from five 3D-shaped panels.

Its 250 laser-cut perforations and Micro Mesh shell are aimed at hot summer motos, and the HeatGrip inner knees give grip without a leather panel.

Key Features

  • Ultra-light Twisted Yarn Micro Mesh shell with 4-way stretch
  • HeatGrip aramid-backed inner-knee panels
  • New, lighter multi-layer I.K.S. against knee-brace wear
  • 250 precision laser-cut ventilation perforations
  • Seamless seat and shaped crotch
  • Waistlock in Hypalon around the full waist
  • PFAS-free DWR C0 80/20 finish
  • Fabric certified bluesign® APPROVED

Who it is for

Supercross and motocross racers who ride with knee braces are the core audience. Low weight, high airflow and a locked-in waist are its main strengths.

Cut and shape

Leatt cuts the 5.5 I.K.S from just five main panels, each with 3D pre-curvature, which gives a form-fitting, anatomical race fit with very few seams. There is no seam on the seat, and the crotch is shaped for the riding position. The waistband closes with a 360° Waistlock in Hypalon. In this colourway you can choose from XS up to XL.

HeatGrip and brace zone

Instead of leather, the inner knees use HeatGrip panels with an aramid backing; Leatt rates their grip and durability above leather. The I.K.S. layers are placed where brace hinges rub, and the latest version is lighter than before. Leatt adds that the HeatGrip knees are easier to maintain than leather ones.

Coating and fabrics

Water beads off thanks to a DWR C0 80/20 coating free of PFAS (PFC). Improved durability in the washing machine is part of the update. bluesign® APPROVED fabric, OEKO-TEX, REACH testing and plastic-free packaging complete the picture.

Light and airy

An ultra-light Micro Mesh woven from twisted yarn, fully stretchy, brings the pant to 660 g in size L. Leatt adds 250 laser-cut perforations to the Micro Mesh. Taped seams, kept to a minimum, help it last.

What you should know

With 250 perforations and a mesh shell, this is a hot-weather race pant, not rain gear. No certified armour is built in; knee guards or braces are worn separately. Sizes for this colour run XS to XL.

Colour

Acid Yellow is a pale lime yellow that fades into mint towards the lower legs, with thin dark line graphics and a black inner knee. The light shade looks fresh and is very visible, but it will show mud and roost marks sooner than a dark pant, so plan on regular washing.
