All-new engines from ‘The Driveline Company’ (also known as TDC).
These V-twin engines are available in three sizes – 99", 115" and 125"
with three finishes – polished, black and chrome, or natural. They’re
‘assembled in America,’ and have many upgrades over other traditional
V-twins. All three sizes feature increased fin areas on the cylinders and
heads, and oil squirter jets under the pistons, for maximum temperature
control and long engine life. The traditional breather system with gear
has a long-proven track record, so it was decided that “if it ain’t broke,
don’t fix it.”
These new assemblies will easily replace all 1984–1999
Evolution-style engines. The specially-designed ‘D’-shaped intake and
manifold ports provide exceptional controlled air flow, and the 45mm
Mikuni carburetor will easily provide enough fuel for all three engine
sizes.
TDC started with a clean sheet when designing all the parts and
tooling needed to bring this new program to life. Extreme attention to
detail for the cases, heads, crankshaft and cylinders was employed to
bring together the special styling, amazing reliability and “unreal” seat
of the pants “torque” for this new product line. Matching transmissions
are also available.
