Yamaha SRX

From Wikipedia, the free encyclopedia

The Yamaha SRX is a standard-style motorcycle that was manufactured in three engine sizes: 250, 400(398)cc and 600cc. Single cylinder, twin overhead camshaft engine with an advanced two stage carburetor and balance shaft; lightweight steel frame; dual front disc brakes/single rear disc; dual shocks; alloy wheels. The 600cc model was originally manufactured for international distribution; the 400cc model was concurrently manufactured for domestic (Japanese) use, but some were unofficially exported. The 400cc model also has an oil cooler and only a single front brake disc. Later development modifications included a monoshock rear suspension and electric start as its shown on the picture. The 400cc model has 38bhp and a top speed of 180km/h. It has air/oil cooling and 5 speeds.

[edit] 1986 Yamaha SRX 600 U.S. Version

1986 was the only year that the SRX was imported to the U.S. The 600cc version (595cc actual)was air cooled, had no front mounted oil cooler and came only in "Maple Red". To top it all off, Yamaha decided to give it the unique distinction of having a kick-start as it's only method of ignition.

Historically, single cylinder street motorcycles have fared poorly on the showroom floor in the US, and the SRX600 was no exception. Nimble handling, light weight, and unique styling were not enough to compete with the heavier, flashier, and much faster multi-cylinder alternatives available for not much more money. As with many similar market wallflowers (such as the Honda HawkGT), the SRX600 has reached cult-bike status in the US.

The cult following that this bike has drawn was recently demonstrated when a Portland, Oregon auction house brought a showroom quality 1986 SRX 600 with only 4 actual miles to the floor of the auction house and the bidding ended at $7500. Considering this bike sold new 20 years earlier for $2495, this is quite a promising appreciation curve and it serves to demonstrate the market's appetite for rare and unique bikes.
