⭐⭐⭐⭐⭐ Ali Raza - Amateur Track Rider
"I installed the KAMTHAI WAVE 125 RS(CH) sprocket kit on my bike before the Lahore Monsoon Cup last season, and the difference was immediate. The 36T/14T gear ratio gives me lightning-fast acceleration out of corners, and the lightweight aluminum reduces rotational mass noticeably. No slippage even at high RPMs—perfect for tight circuits."Purchase Date: April 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Sana Khalid - Urban Commuter, Islamabad
"I was skeptical about upgrading from the stock steel sprockets, but this KAMTHAI kit has made my daily commute smoother and more efficient. The gold aluminum finish looks stunning, and I’ve already noticed a slight improvement in fuel economy—probably due to the reduced weight. Installation was straightforward with the included hardware."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐☆ Fahad Mehmood - Adventure Biker, Balochistan
"Used this sprocket set on a recent off-road trip through Ziarat’s rocky trails. The lower gear ratio really helped with low-end torque when climbing steep inclines. While it sacrifices a bit of top speed, the trade-off is worth it for rugged terrain. The aluminum shows minor scratches, but no signs of cracking or deformation."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Imran Sheikh - Home Workshop Owner, Karachi
"As someone who modifies bikes in his garage, I appreciate how precisely these sprockets fit the Yamaha Wave 125 RS(CH). The Thailand CNC machining ensures zero wobble, and the polished finish resists corrosion even in humid coastal areas. I paired it with a new chain, and the entire drivetrain runs whisper-quiet now."Purchase Date: August 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Arslan Malik - Performance Tuner, AutoXpress Racing Garage
"We’ve fitted this KAMTHAI sprocket kit on three customer bikes now, and all reported improved throttle response and better hill-climbing performance. The 22% reduction in rotational mass makes a measurable difference in dyno tests. For riders in Pakistan looking to upgrade without breaking the bank, this is a no-brainer."Purchase Date: January 2025 | Usage Period: 6 months

Eng. Tariq Hussain - Automotive Dynamics Specialist
"The KAMTHAI 36T/14T configuration delivers a scientifically optimal gear ratio shift for the Yamaha Wave 125’s engine curve. Combined with the heat-treated aluminum alloy, it offers superior power delivery and thermal management over steel alternatives. I recommend this kit for riders prioritizing acceleration and urban agility."
Captain Naveed Ahmed - Pakistan Adventure Riders Academy
"For training riders on mixed terrain, we’ve started recommending the KAMTHAI sprocket due to its balanced performance. The 12% lower gear ratio improves control on loose surfaces, which is critical for beginner-to-intermediate off-road riders. It’s also durable enough to handle Pakistan’s harsh dust and gravel conditions."
