Yamaha has re-introduced its famous SR model in the U.S. this summer The 2015 SR400 is virtually the same bike as the SR500 which was sold in the U.S from 1978-1981. Production of the SR500 ended in 1999, however the SR400 has been sold exclusively in Japan since 1978. It has a different crankshaft and a shorter piston stroke than the 500 and electronic fuel injection was added in 2010 to meet ever-tightening emission standards, but not before causing a two-year hiatus in the bike's availability. Now it's back, and after arriving in Europe and other parts of Asia last year, it's available in the U.S.
I picked up my new bike June 25th 2014, the first unit to arrive.. from the same salesman that sold me a new 1979 SR500. We were in our twenties then..Scott is 60 now and I turn 55 next month. I feels like my old SR500.. with a smoother engine and an easier clutch. Started it a few times on the first kick (one time in two kicks). Very smooth idle, and no choke or hot start button to fiddle with thanks to the EFI. Power feels close to the 500. After all, it is the same engine while making 6 less hp. It feels less thumpy at slower speeds and the lower torque is evident, but it accelerates as well as the 500 and more eager to rev through the gears. Brought it up to about 65. Kept altering the speed, following the break-in procedure. The ride comfort and handling is awesome, like I remember. The bike is well balanced and responsive, and the seat is noticeably more comfortable. It was very windy but the bike was unaffected. With the threat of bad weather I'll have to show it off another day. The quality is top-notch and the bike looks even pricier than it is. The spoke wheels are nicely finished giving the bike a classy, vintage look lacking on the original. The engine finish is high and the paint and chrome are flawless.
The bike is produced in relatively small numbers. According to Yamaha' s Japanese web-site, 1,300 units per year are being produced for Yamaha's Japan home market, while only 500 units will be imported to the U.S this year.
Yamaha must be very proud of this model, building it as long as they have, because although the bike has remained virtually the same in design for 36 years, much refinement is evident and it looks and feels like t's built, not to a price, but with a lot of care and pride.
