Description
Small-bore dirt bikes and mini machines chew through tubes fast because every landing and rock strike gets transmitted straight through a thin sidewall, so the Bridgestone TR4 tube in 90/100-14 is built with enough rubber thickness to take that abuse. A tube that fails mid-ride on a mini bike usually means the day is over, so it pays to start with rubber that can take a hit. Rock strikes and rim pinches are the two most common ways a mini bike tube fails, and the thicker wall on this build gives it a real shot at surviving both instead of blowing out mid-lap.

This tube is cut to the 90/100-14 spec, so it fits straight in on the next tire change without hunting for an odd-size substitute. IPD Racing stocks this size for riders and shops that go through youth and mini bike tubes regularly during a race season, since these smaller sizes tend to move fast once practice season starts.
