A mixture of A roads & B roads, some nice open sections and
although villages on route these are small and short speed limits.
There are some nice bends after Spalding heading toward Bourne,
followed by an excellent straight - just be careful as the bumps can
unsettle the bike at speed. After Bourne there is nice B road,
surface is a little worn/uneven in places but otherwise nice open bends,
just be careful of a few farm entrances which can have mud littered
across the road. Police presence is light but I have seen mobile units
