A must if you are tuning!
"Larger big end and roller little end... What's not to like?! As soon as you start increasing cc or even making it spin harder with a better 50cc barrel / larger carb, a 'race' crank should be considered a must-do. Looks well machined and a hollow big end pin should help to offset any potential balance issues from the larger big end assembly" Jerry Thurston - Friday, December 10, 2021
