Honda SL70 Motosport: Since the invention of the minibike in the 1940s major manufacturers have worked tirelessly to bring their groundbreaking motorcycling designs.
One of the major players was Honda whih jumped onto the bandwagon by launching the 1971 Honda SL70. We will learn more about this lesser-known but highly valued two-wheeler in our guide.
The Honda SL70 (a.k.a. the Honda Motosport(TM) 70) was a motorbike with a capacity of 72 ccs made in 1971 between 1971 and 1973. The two-wheeler had a more stock chassis with oil-damped telescopic suspension forks and a striking, classic exterior.
It was among the first minibikes with an engine with four strokes and a four-speed manual transmission.
Although it was not as popular as legendary bikes like Super Cub and the Z50 money Bike as well as Super Cub, Super Cub, the Honda SL70 was well-loved and celebrated for its functionality and easy-to-use.
It was a great success in the minibike marketplace and eventually changed into the XL70 and improved the dirt-road abilities of the bike. It’s a wonderful souvenir as it’s the size of a miniature TT racer. go through the article and find out more about this classic wheeler.
The Honda Motosport(TM) 70
Many might argue it’s not a good idea to say that the Honda S70 is not up to par with that of the Yamaha JT1.
It did receive its nickname Mini Enduro for a reason in the end. If it was on the same level, the most obvious answer would be yes.
But there are places that the motorcycle Motosport(TM) 70 excels, where it doesn’t – and vice versa.
1971 and 1973 between 1971 and 1973, the Honda SL70 was one of the earliest forerunners to miniature Enduro segment, in spite of arriving a bit late in the race scene.
It was also very like the CT70 series with respect to general design appearance, feel, and colors.
However, it was a bit different from the standard with its four-stroke engine, a 4-speed manual transmission, as well as the absence of a moniker for animals.
It was well-constructed and was available in a road-legal version, beating Yamaha’s renowned JT1 bicycle by nearly a full year of production. In addition, its suspension is superior to the competition in all aspects.
The extra weight could cause it to have a few negatives, but it also made it an extra solid and sturdy structure.
This is the thing that currently makes it an absolute favorite for knowledgeable mechanics and smart owners.
Here is a list of the entire SL70 Honda models released during its three-year existence:
|Year / ID||Colors|
|1971-1972 SL70KO||Summer Yellow, Aquarius Blue, Light Ruby Red|
|1973 SL70K1||Candy Riviera, Fire Red, Candy Yellow|
A Defeated Overachiever?
Honda is always been praised for its inventiveness, second only to its superior quality.
But, this combination strategy has not always resulted in the best results, as is the instance in the case of Honda SL70.
After having had a huge breakthrough in 1969 thanks to the Monkey Bike and its out-of-this-world Dachshund-like design, Honda opted to employ the same method.
However, for the SL70 Honda, it could have gone overboard in its design.
The Honda SL70‘s tiny build was a bit tinny and had nothing to have to do with it. Honda tried to create the bike in the best way it could.
But due to its size, the SL70 was deemed to be far too big for the size, affecting its overall performance, making it an option for those who enjoy building projects rather than for children.
In addition, it was obvious that the bike’s speed and torque output were in second place to other 70-cc Honda models at the time.
It was a bit of a disappointment that the Honda SL70 was perceived as more of a maintenance hog than its two-stroke counterparts.
This was an advantage for aftermarket parts dealers that specialize in transforming the anvil-like motorcycle into a beast of performance, however, it was only a few years after the minibike’s production stopped.
Honda SL70 Specs and Features
The SL70 Honda has a uni-cylinder, four-stroke OHC engine layout, tempered by an effective air cooling system, similar to its minibike counterparts in the same class.
It is equipped with a displacement of 72 cubic centimeters (4.4 inches) and a (slanted) horizontal design of the cylinder that permits it to meet licensing standards.
Bore-stroke ratio of 47 and 41.4 millimeters (1.85 1.85 x 1.63 inches) and compression ratio 8.8:1.
While it shares many of the engine specifications of the CT70 however, the SL70 features a smaller 15-mm piston valve-type Keihin carburetor for the air-fuel mixture.
Air filtration is an excellent foam-filled, oiled polyurethane filtering component. Its strength and durability contribute to the minibike’s top speed of 32 miles per hour (52 kilometers/h) and a horsepower produced at 6.44 HP (4.8 kW) at 9,500 RPM.
But other magazines like Cycle World Magazine mention the SL70 emits as little as 5.0 horsepower (3.7 kW) at 8000 RPM.
Luckily, mods can increase not only the bike’s ponies but also it’s top-speed rating to as high as 77 mph (124 km/h) or more – depending on the increase in bore size, plus other performance-enhancing elements.
The conversion to the PE28mm Nibbi Racing Performance Motorcycle Carburetor (view on Amazon) is certain to boost these numbers by two times.
Fuel & Lubrication
The fuel tank’s capacity can be 1.7 US gallons/6.4 liters (including reserve) of gasoline that is unleaded with the minimum PON 87 or RON91 rating, which contains five percent Methyl Tertiary Butyl Ether and 10 percent ethanol or five percent methanol along with corrosion inhibitors and cosolvents.
For motor oil, Honda advises 0.7 liters/0.74 US pints in Honda G4 SAE 10W-40 or it’s equivalent for the SL70’s Forced Pressure (wet sump) fluid lubrication system.
Motor oils that have an API Grade of SJ or greater (without Molybdenum and graphite add-ons) that meet JASO standard T903MA/MB provide the most effective results.
It is also possible to use other viscosity grades based on specific ambient temperatures:
SAE 30 (above 15deg C/60degF) or SAE 20W (-10deg to 15deg C/60deg-90deg F) or SAE 10W (below the 0deg mark and 32deg F) or SAE 20W-50 (above 10deg C/15degF).
It is the Honda SL70 has a primary kick-starter that is paired with an O-ring chain of 420 links (96 links, including a joint) which delivers energy into the earth.
It was a departure from the traditional two-disc wet clutches that are found on the majority of mini trail bikes from the manufacturer and was modeled following the CT70H models that have an automatic 4-speed constant-mesh gearbox.
But, be aware that the reduction ratios for the primary and final between the two are totally distinct from one another.
The front and rear sprockets of 1991’s Honda SL70 are 13/44T. Information about gear ratios on this model is very rare. But here are the 1st to 4th gear values for the 1973 model (source: MotorbikeCatalog.com):
|Primary Reduction Ratio||3.722|
|Final Drive Ratio||3.615|
|Transfer Gear Ratios||1st – 2.692 (36/22) 2nd – 1.824 (24/54) 3rd – 1.300 (17/49) 4th – 0.958 (12/89)|
The 6V breaker point-of-ignition is controlled driven by a flywheel magneto, and an AC generator acting as the source of lighting and charging system.
It requires the 6-volt 2 Ah/(10 HR) 6N2A-2C/3 battery or B60-6 with dimensions of 2.75 x 1.88 and 4.19 inches (70 47 x 101 mm – the dimensions of L, W, and H) and an NGK C7HSA spark connector with a 0.6-0.7 millimeter gap.
In the event of a spark plug failure, it is recommended that there be replacements available. NGK C7HSA plugs come with more than 19 plug replacements comprising Bosch 0241045001 U5AC and U6AC kinds. I strongly recommend making use of the Spark plug locater to your convenience.
If you wish to make your pocket bike street-legal across the fifty U.S. States. In this case, you’ll have to convert the electric system into 12V in order to allow the motor meter (view at Amazon) as well as the YTX4L battery, and installation of an electronic horn as well as other items.
Talk to a professional mechanic or your local dealer about the next steps to take for an effective 12-volt conversion. Honda Forums are a good starting point for study.
Tires & Brakes
The front 2.50-16 tires as well as 2.75-14 rear tires have aluminum wheels. They are not interchangeable with the Honda Trail CT70 or Z50 because their rims are a bit larger.
They can withstand large bumps and ruts, but they are more comfortable on smoother surfaces and relatively technical roads.
Therefore, the stock tires are better suited to be changed to wire spokes with lace and bias tires, or radials.
In terms of stopping power, the expanding drum brakes on the front and rear complete the SL70 wheel and tire assembly.
The double-cradle frame, single-backbone is home to front forks and comes with springs that are internal, delivering remarkable damping.
The rear shocks, which are lubricated, are wound in a progressive manner, but they have unadjustable damping.
This design of suspension works with the bike’s 44-inch diameter wheelbase it is not bend-proof and prevents flex in addition to providing 4.4 inches of road travel.
Even though it’s set by the factory to be soft, the handling remains adequate off-road, keeping it from bottoming out and minimizing fatigue of the rider above what is typical of two-wheelers this big.
Dimensions & Capacities
It is the Honda the SL70’s total dimension include 67.5 x 28.3 and 26.5 inches (1,715 719 x 719 x 673 mm LxWx H). When compared to the CT70H the SL70 is taller and wider, however, it has a smaller seat height.
Many riders regarded these dimensions to be perfect (the Goldilocks’s zone) which was a popular feature of the minibike in the early days of its production.
Based on the year of production of the minibike dry weight may range between 54-65 kg (119-143 pounds. ) and curb weight without the weight of the rider is 69-72 Kg (152-159 1 lb.). Based on these estimates the SL70 is just a bit heavier than its comparable models.
It is confident that the gross vehicle weight rating will not exceed 288 kilograms (635 pounds.) However, it is recommended to verify this against the specifications in the instruction manual.
In contrast to the CT70 series unlike the CT70 series, the CT70 series, Honda Motosport SL70 did not come with as many variations or trimmings.
It was only in operation for a three-year time frame The pocket bike was available in just six (6) color options for the body including three namely:
Summer Yellow, Aquarius Blue as well Light Ruby Red (1971-1972) as well as the Candy Riviera Blue Fire Red, and Candy Yellow (1973).
In its original form, it was simple to discern the year of manufacture in the same way.
However, this could be a challenge for used bikes that have had a new paint job. Even if the bike was subject to restoration, later models had the same body colors based on candy that were used in the CT70s.
If the original colors of the body were preserved, the most effective way to determine the year of production was to look at the logo, the tank-and-shroud finish, and the instrumentation.
The initial two seasons of Honda SL70 had a blue emblem and a blue-and-red SL70 logo that read. The Summer Yellow SL70 had a black stripe on the tank that was distinct from the normal white used on other models.
A speedometer analog was available. In contrast, the 1973 model came with a fuel tank as well as “70” decals in yellow.
The base models were now equipped with the speedometer, tachometer, and trip meters as standard features. Honda SL70 parts appear to they were sourced from higher-performance, larger Honda motorcycles and restricted to the minimal amount.
Turning the SL70 Street-Legal
From the crate, it appears that the Honda SL70 has the requisites to legally ride on pavements – however, not every one of the fifty U.S. states. The 44-inch wheelbase does not meet the minimum length requirements in two places.
The bike was initially not equipped with a horn or a speedometer kit until the final year of production. Furthermore, its 6-volt electrical system is problematic and requires to change to 12V in order to make the distribution of light and charging more reliable.
With tighter licensing requirements in various nations, you could require more than just a few instruments and a horn to ride this motorcycle. Fitting it with rearview mirrors as well as a holder for license plates, and tires that are DOT-approved (among other things) is strongly recommended.
A muffler from aftermarket is not required because the SL70 already comes with an approved Krizman U.S. Spark arrester that is Forestry-approved. Similar is the case with changing the engine to 150/200-cc specifications.
Price of a Honda Motosport(TM) 70
