1983 Yamaha XJ 650 Seca Turbo

TURBOCHARGED MOTORCYCLES ARE HOT NEWS THESE DAYS. besides being the flashiest things on two wheels. not to mention expensive. and still fairly rare. With the Suzuki XN85 waiting in the wings. today's potential turbo owner has to agonize over just two choices: the Honda CX500TC. and Yamaha's new XJ650LJ. their makers' (and. the world's) first catalog-model Turbo bikes. There being just the two. comparisons are inevitable and. as it happens. most interesting. Both the Honda Turbo we tested last month and the Yamaha Turbo presented here have force-fed engines and high-tech styling. But they really are not very similar at all. In the real-world sense Yamaha's Turbo is a somewhat smarter effort than its rival precisely because fewer surges of brain power were expended in its making. Honda built the CX500TC to hook all the hardware junkies. enhance the prestige of its engineering staff. and to let everyone know what can be expected from a mere 500 cubic centimeters displacement when the filling is done with a tamper. For such reasons. and because the CX500 V-twin only reluctantly lends itself to tubocharging. Honda made its Turbo a fuel-injected. gadget-laden. technological tourde force. By contrast. Yamaha seemingly borrowed from the Honda advertising slogan "We make it simple" for inspiration when the XJ650LJ was being designed. They made it simple.
