The heart of any bike is the motor, and the Revolution X in the Street 750 is a worthy successor to the Revolution engine from the V-Rod. While the V-Rod has decent bottom-end torque, it really comes on in the midrange and just keeps pulling to redline. The Street starts mellow, hits hard in the middle, and tapers a bit on top. It’s a good combination for a bike that's aimed at the entry-level market; capable of thrilling an experienced rider, while giving a beginner confidence. Riding it, you definitely feel the family resemblance to the V-Rod, both in power delivery, as well as sound, which combines the high-pitched whine of the top end with a low bass from the exhaust pipe.
Unusual for a cruiser in this price range is the six-speed transmission, too. Unusual for a Harley-Davidson, that transmission is also light shifting, but slightly vague, whereas most other H-D transmissions are heavy shifting, but positive. The ratios are also well-matched to the powerband; first seems slightly tall, and 6th will pull right past 80. The skinny clutch lever does, however, allow for two-finger operation, which is also unusual for this brand. While there is no tachometer, the midrange is so meaty and the motor revs so high, it’s not really needed.
