Freeline Wheel Set 5 DF130-DF180M HQ

The Freeline Wheel Set DF130-DF180M is a 5-inch magnesium wheel set from Freeline — the official component brand of Birel ART. This set pairs a 130mm front wheel with a 180mm rear, offering a mid-width rear configuration suited to circuits where a wider 210mm rear would generate excessive grip or where the regulations specify a narrower tyre profile. Manufactured to OEM specification for Birel ART Group chassis.

Buying Advice

The 180mm rear width sits between the narrow 130mm and wide 210mm options — a common choice for classes with specific tyre-width rules or tracks requiring a softer rear-end grip level. Related: Kart Wheels | Wheels.
