Development
The Topper H was introduced in 1961 (sold through 1965) with a new alloy cylinder head that increased the compression ratio to 8.0:1, the transmission placed in a sealed oil bath, a reusable foam air filter, and revisions to the cylinder ports and air intake tube.
A detuned version of the Topper was also available, with the power restricted to 5 hp (3.7 kW). This was advertised as the "Topper U".

Famous quotes containing the word development:
“Women, because of their colonial relationship to men, have to fight for their own independence.

Only the independent woman can be truly effective in the larger revolutionary struggle.”

“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
