Upgrade your YZ-870C with the Yokomo YZ-827-2 rear wheels to move from the vintage 1.9-inch fitment to 2.2-inch tyres. The larger profile improves contact patch and traction on both loose surfaces and indoor carpet lines, helping you dial in better handling.
The YZ-827-2 keeps the YZ-870C hub geometry while increasing overall diameter to suit current 2.2-inch tyre ranges. Expect a wider tyre choice and altered gearing needs; reducing pinion teeth is a common tweak to compensate for the larger tyre circumference.
These wheels are supplied without factory air holes so you can cut ventilation tailored to your conditions. Use a small drill or a taper reamer and try conservative hole sizes first to maintain wheel strength and airflow control.
