Yes, it is generally possible to replace a 120/80-17 tube-type tire with a 100/90-17 tubeless tire on a Bajaj Pulsar 150cc motorcycle. However, there are a few important considerations to keep in mind:
Wheel compatibility: Ensure that the wheel size of your motorcycle is compatible with the new tire size. In this case, both tire sizes have the same rim diameter (17 inches), so they should be compatible.
Clearance and fitment: Check if there is enough clearance in the bike's chassis, swingarm, and fenders to accommodate the wider tire. Additionally, confirm that the tire fits properly on the rim and aligns with the brake components without any interference.
Handling and performance: Switching to a narrower tire may affect the handling characteristics of the motorcycle. The wider tire provides more contact patch, which can improve stability during cornering and braking. The narrower tire may result in slightly different handling and grip characteristics.
Tubeless conversion: If you switch to a tubeless tire, you'll need to ensure that your bike's rims are compatible with tubeless tires. Tubeless tires require rims with specific sealing properties to hold the air pressure without a tube.
It's important to consult with a trusted mechanic or an authorized service center to ensure that the tire swap is suitable for your specific motorcycle model and riding needs. They can provide accurate guidance based on their expertise and familiarity with the bike's specifications.
