Additional FeaturesMoved to Sevcon, not as easy to tune as the Kelly was.
APRS GPS transmitter/Receiver.
Changed brake and headlights to LEDs
Sevcon is working great after a while.
Had to program it so reverse is actually forward direction.

Moved to a 420 chain from 520 chain.
60T rear and 18T front. Much lighter now.
Also can hit 90+mph.

Had a 16T from a 14T to get more highway
speed. Also it quieted
up the chain so now it is super silent.

I absolutely love riding the bike up the
twisty canyons.
