⭐⭐⭐⭐⭐ Jake Reynolds - Recreational Rider
"I installed the CQSPMOTO Pro Model clutch assembly on my 125cc trail bike back in February 2025, and it’s been a total game-changer. The automatic clutch mechanism eliminates hand fatigue on long rides through rocky terrain, and I’ve noticed significantly smoother power delivery. The aluminum body stays cool even after hours of aggressive riding—no overheating issues. After 6 months of weekend trail runs, it still performs like new."Purchase Date: February 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Lucas Mendez - Motocross Technician, Apex Racing Squad
"We’ve been testing the Advanced Model with our junior 110cc racers since November 2024, and the results speak for themselves. The 17-tooth design delivers faster, more consistent gear engagement, which is critical during tight corner exits. We’ve also taken advantage of the adjustable pressure plate to fine-tune clutch feel for different track conditions. With over 200 race hours logged, durability has exceeded expectations—zero failures or slippage."Purchase Date: November 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Amanda Cho - Custom Bike Builder
"I built a custom 90cc dune runner for a client and chose the Base Model for its balance of cost and performance. Installation was straightforward, and the modular design made it easy to swap in aftermarket friction plates. I especially appreciate the replaceable steel fasteners—they’ve held up perfectly through sand and mud exposure. After 5 months of use, only minor cleaning was needed. Would’ve given 5 stars if the adjustment range was a bit wider out of the box."Purchase Date: January 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Diego Herrera - Off-Road Rental Business Owner
"Running a fleet of 70cc–125cc bikes for dune tours, reliability is non-negotiable. Since switching to the CQSPMOTO clutch assemblies (Pro Model) in April 2024, maintenance downtime has dropped by nearly 40%. Riders—many of them beginners—love the automatic clutch because it makes riding accessible without constant stalling. Even with daily heavy use across harsh desert conditions, the composite-reinforced plates show minimal wear. Heat dissipation is outstanding; no thermal degradation even in 110°F heat."Purchase Date: April 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Tara Williams - Mountain Trail Guide
"As someone who leads beginner-to-intermediate off-road groups, I need gear that’s both durable and rider-friendly. I upgraded my personal 110cc trail guide bike with the Advanced Model in September 2024. The lightweight design (1.1kg) improved bike handling, and the anodized aluminum resists corrosion from rain and creek crossings. The automatic clutch lets me focus on terrain navigation instead of clutch control—huge plus during steep climbs. After 8 months of frequent use, it’s still running strong."Purchase Date: September 2024 | Usage Period: 8 months

Alex Turner - Off-Road Drivetrain Specialist
"Having evaluated dozens of clutch systems, I can confidently say the CQSPMOTO 17-Tooth Clutch Assembly sets a new benchmark for small-displacement off-road bikes. Its aluminum 7075 construction with ceramic coating (Advanced Model) offers a rare combination of strength, thermal efficiency, and weight savings. The fact that it exceeds ISO 9001 standards and delivers 22 Nm of torque capacity makes it ideal for both recreational and professional applications."
Coach Elena Ruiz - Youth Motocross Academy Director
"We’ve integrated the Base and Advanced Models into our training fleet because the automatic clutch reduces cognitive load for new riders. This allows them to focus on throttle control, balance, and line selection—critical skills in early development. The durability and ease of maintenance also make it a smart investment for any riding school or rental operation."

"Replaced a worn OEM clutch on my 125cc quad. Fitment was spot-on, and the adjustable tension lets me dial in the feel. Only downside: instructions could be more detailed for first-time installers."
