| The '''[[Honda]] SL70''' was a single cylinder, [[four-stroke]] Naked [[motorcycle]] produced by [[Honda]] from 1971 to 1973. Claimed [[horsepower]] was 6.44 HP (4.8 KW) @ 9500 RPM.
| |
| | |
| | |
| ==History==
| |
| | |
| In 1970 Honda wasn’t going to let [[Yamaha]] cash in on the new mini-cycle craze with their
| |
| [[Yamaha JT-1|JT1MX]], so [[Honda]] Motors Corp’s design facility in Torrance, California came up with the SL70, a scaled down 70cc version of the on-off road Honda SL motorcycle line .
| |
| | |
| Coincidentally, the SL70 closely resembled the 1969 [[Honda SL90|SL90]], down to the tank/frame design and slanted cylinder configuration. In standard Honda fashion, the SL70 looked good, and seemed ready to take on the Yamaha mini-enduro in all areas.
| |
| | |
| Unfortunately a few typical Honda design features of the time, like excessive weight and over-engineering cursed the SL70 with a dry weight of 153 lbs, versus the relatively light weight of its competitor, the Yamaha Mini-Enduro at 121 lbs, wet.
| |
| | |
| Not to say the SL70 was a pig, as thousands of die hard Honda fans snapped up the mild little 70cc buggers for their kids, and even themselves, under the guise of a “pit bike”. And of course, all the Honda hop up aftermarket folks like Poweroll and Webco produced kits to up the SL from its anemic 6.5 horsepower to fire-breathing configurations with high lift cams, big carbs, stroked cranks, big bore kits, etc. Even a Poweroll 110cc kit was offered, that required the owner to bore the cases, stroke the crankshaft, and run a paper-thin steel cylinder liner. Such was the life of a hopped up Honda 4 stroke motosport owner, who sacrificed anvil like reliability for performance.
| |
| | |
| Seeing that the SL70 was to compete against its closest rival, the [[Yamaha JT-1|Mini-Enduro]], Honda did see fit to equip the SL70 with better forks and shocks than the Yamaha, and the SL came in a full street legal configuration, unlike the Yamaha which would wait to release a lighted version of the [[Yamaha JT-2|JT2MX]] in 1972.
| |
| | |
| Compared to the Yamaha Mini-Enduro, the SL70 was a well constructed, solid Honda that suffered from excessive weight and higher maintenance than its two-stroke rival. As one who lived the period, and competed against the Honda, the only bad thing I can say about it was the Honda level of thrash-ability that allowed riders to run the poor little bike on the ragged edge of with no-maintenance, that would ultimately cause the bike to explode, and render it a useless expensive door stop.
| |
| | |
| | |
| The SL70 lived on until 1975, renamed the [[Honda XL70|XL70]], and was actually replaced by the [[Honda XR75|XR75]] in 1973, a totally different machine, with a vertical cylinder configuration, and a lighter weight of 140 lbs. 1973 was a milestone year for Honda, with the release of the [[Honda CR250|CR250]] and [[Honda CR125R|CR125 MX]] machines. After ’73, Honda never looked back.
| |
| | |
| | |
| ==Engine==
| |
| The engine was a [[air cooled]] single cylinder, four-stroke. Fuel was supplied via a overhead cams (ohc).
| |
| | |
| ==Drive== | |
| The bike has a 4-speed transmission.
| |
|
| |
|
| ==Chassis==
| |
| Stopping was achieved via Drum in the front and a Drum in the rear.
| |
|
| |
| ==1971 - 1973 Honda SL 70==
| |
|
| |
| Honda's SL 70, manufactured between 1971 and 1973, had a 4 speed transmission and a 4 stroke air cooled single cylinder, single overhead cam engine.
