Tommy Robb on the RC112:

"I must admit the 50cc Honda Twin (on which I won the first "All
Japan GP") was my favourite 50cc bike, it was considerably better
than the earlier single. Very smooth, excellent power and the handling
was superb. It was also an excellent riding position and didn't feel
as cramped as the old single.
Of course the bike I rode was very much the prototype and this kept
improving after I then left Honda and became better and better with
every race, as proved when it eventually won the World Championship
from Suzuki after many years of trying.
I was very disappointed that after that first win at Suzuka that my
contract, and that of Takahashi, was withdrawn for the 1964 season
when Ralph Bryans went on to win the Championship".

Honda rim brake. "The RC113 Twin 50cc was a beautiful little bike and the "push bike"
rim block brakes actually worked exceptionally well, although it took a
lot of bravery when coming into an acute hairpin from 115mph to apply
a lot of pressure and hope that these little brake blocks would perform
as they should.....but they did."

Honda production racers

The CR110 were available to privateers 1962 through 64 and were used in club racing for many years. Developed by professor Suzuki of Hondas race department, the CR110 came in two batches. The second batch had 8- speeds instead of five, and the points moved from inlet- camshaft to crankshaft.

The CR110 were presented at the Earls Court motor show by Geoff Duke

"I was so impressed with the little Honda that I duly bought it and so
began a reasonable successful period of 50cc racing.
I regret not getting further than the bottom of Bray Hill in the
1968 Isle of Man TT,after being 3rd fastest in practice behind
Barry Smith works Derbi and R.Kunz Kreidler. A valve dropped
in wrecking engine.
The little Honda served me well and I won many events with it
and was mostly placed in the top 3. This included 3rd overall
in the 1969 ACU Star British Championship and 2nd runner up
in the same series of events in 1970."
