Engine and Performance
The Street 750 is powered by an all new 749 cc V twin liquid cooled “Revolution X” engine. This 60 degree V twin gets a 4 valve head and boasts of 85mm X 66mm, bore X stroke. Reportedly, this mill can rev up to 11000 rpm. As per the specs, it produces 60Nm @ 4000 rpm, however the power figures are rumoured to be between 50-55 bhp (H-D never reveal bhp figures). Never mind the bhp figures, V engines are loved for their grunty torque and that’s what the Street 750 has in oodles. Like all Harley-Davidson bikes, power transmission to the rear wheel is via a toothed belt, which liberates one from the hassles of lubrication and adjustment of a chain drive.
The 750`s V twin is mated to a 6 speed gearbox which clunks through the cogs with reassuring feel. The clutch is surprising light, however could have had a more progressive feel. Riding it along the traffic isn’t much of a wrist workout since the torque-y nature of the mill demands minimal swapping in between cogs. Such is the nature of its potent bottom end torque that the bike pulls away clean from 35 kmph in 6th gear!
Despite being a liquid cooled power plant the head radiation does become a bother while trundling along the urban traffic. The liquid cooling also minimizes the V twin roar and leaves it with whirring burble. The `Screaming Eagle` exhaust and air filter will certainly help the Street 750 gain some more aural grunt.
The engine exhibits an eagerness to rev and does not hesitate at the slightest twist of the wrist. The V twin remains the happiest within the low to mid range of the rev band and does get slightly harsh towards the top end. Keep the throttle wide open and the 750 will hit 170 kmph, however the wind blast makes riding at speeds above 140 kmph quite tiresome.

nice review with photos
Hopefully Harley will take note of the un-impressive aspects and work towards improving them. Tyres can be swapped for a stickier pair, mirrors can be replaced by more functional ones from the RE Thunderbird. But practically nothing can be done about the weak brakes and weird foot-peg placement. Maybe an after market job on the pillion seat could make it a better place to be in. Lack of a fuel gauge is a major grouse, hoping Harley incorporates one or atleast makes it available as an accessory………….
it is better…..
Clarke- you said it. Its only a start. Hopefully it keeps growing and growing for Harley. Already some talk going on with the forums. HDforums.com and hdstreetforum.com are talking about this bike.
So here you go: Cruddy tires, funky pegs, weak disc brakes, un-impressive metal work on the tank. I'm glad Harley is breaking into the world market in the critical mid-size market. But, they've got a ways to go to catch up with any of the big 4 from Japan on quality and workmanship. It's a decent start, but only that. A start.
