METZELER TUBE 4.50-5.10 -17 150/60-160/60-130/70-140/70-150/70-130/80-140/80-150/80-130/90 -17 TR4 (CTN 18)

The Metzeler TR4 is a motorcycle inner tube for 17-inch wheels, covering a broad range of tyre sizes in both conventional and metric fitments.

This tube suits tube-type tyres used on road bikes, tourers, and dual-sport motorcycles. It spans metric sizes from 130/70 through to 160/60 and 130/90, as well as conventional widths from 4.50 to 5.10 — all on 17-inch rims. The TR4 straight metal valve is a standard fitment on most motorcycle wheels, allowing straightforward inflation with any tyre gauge or pump.

Metzeler is a well-established European motorcycle tyre brand, and this tube is designed to complement both their own tyre range and general aftermarket tube-type applications.

Lightly dust the outside of the tube with talcum powder before fitting to prevent it sticking to the inside of the tyre.
Partially inflate the tube before seating it in the tyre so it holds its shape and avoids folds or pinches during installation.
Use proper tyre levers and take care not to pinch or nick the tube against the rim when mounting the tyre.
Check and set tyre pressure after installation once the wheel is back on the bike.
Check tyre pressure regularly with a calibrated gauge; never exceed the maximum pressure stated on the tyre sidewall.
Store unused tubes in a cool, dark location away from direct sunlight, ozone sources (motors, fluorescent lights), and petroleum-based products, which degrade rubber.
Inspect for slow punctures by partially inflating the tube and submerging it in water — air bubbles reveal the leak site.
Replace the tube if it shows cracking, has been stretched beyond its size range, or carries multiple previous patches.
