Customer Reviews for RevTech 125″ Wrinkle Black Engine 

Overall Rating:
5/5 based on 1 rating

5 by

Fit perfect, tons of power. I wouldn't do a stage 1, 2, 3 or other bolt mix match of stuff ever again. This fits perfect, tuned and engineered top to bottom for the power output. Very happy, scary insane power for an old 92 softtail custom. Puts a smile on my face and tightens the ass cheeks every turn of the throttle.
