My first bike was an SL-70, not big on speed, but so much torque I once dragged a 20" Dia. felled tree up a paddock hill (helping mum do a bit of landscaping age 10). Cool. The SL100 was like a superbike to me, until a friends older brother showed up on a shiny new XL125.....
Another retro Namco crazy biker game - this one's a bit more Judge Dredd than Ultraman
This wild tracker has an evil 100cc's of power, nickel finished frame and custom made everything. It was built by Dave Miller for a client - He's been involved in MX since the late 70's and makes jaw-dropping Vintage track bikes - check out his page:http://www.davemillerconcepts.com/index.php
Moriwaki was behind some great names in racing like Gardiner and Phillis, and still manufacturing & racing today in Moto2 class and others. Always very exotic to my 70's eye.
