The Holland you are not expecting of nature, history and motorcycles

Assen,the provincial capital of Drenthe, is actually a0 modest-sized town whose name is heavily associated with the TT Circuit.
The surroundings of Assen offer many opportunities to learn about the most characteristic Dutch regions, to explore bike riding travelling towards the North Sea, passing the lake basin of Paterswoldsemeer, born from the excavation of peat lands along the border between the two provinces of Drenthe and Groningen before merging into a picturesque landscape dominated by the typical coloured wood houseboats.
The passion of the Dutch for motorcycling is evident from the broad, bright streets which enable you to thoroughly enjoy the scenery up to Groningen. Famous throughout the world for its university, this town offers a panorama of harmonious coexistence between the modern and ancient. A positive and electrifying charge is given to all riders from the view of the Groninger Museum, whose eccentric structure is coloured by a team of architects led by the Italian Alessandro Mendini. Positioned on an island along the Verbindingskanaal, it houses art collections for all tastes.

Driving northward means reaching the Waddenzee, a small open-air paradise: the coast in the far north of Holland has long offered rolling plains inhabited, among others, by wonderful seal colonies. Included in the UNESCO heritage for the incredible variety of flora and fauna, it offers unique landscapes and fresh, health air to breathe deeply. 
While you are admiring the scenery you can taste a slice of the delicious Groninger Koek, a sweet similar to a soft loaf typical of this area and prepared using rye flour, ginger and cinnamon.
In an exciting drive the aquatic expanses of this corner of Holland which borders the adjacent region, Friesland, until you get to its most important centre, Leeuwarden. The town famous throughout the world for its flower market, Leeuwarden is located in an area that is home to the longest chain of interconnected lakes in Europe, in addition to the numerous channels that provide a romantic and exciting image to the travelling biker.
Holland is also the country of windmills, but in Leeuwarden ... only one survives, called Froskepôlemolen and it is still accessible. Once the skyline of the capital was dominated by these characteristic buildings, but they subsequently fell into disuse in the last century and finally faded out. To take a nice souvenir photo of your journey on the road - along with that unmissable one, in front of the main entrance of the TT Circuit - you can drive up to Oldehove, the most famous leaning tower of Leeuwarden and in the whole of Holland.
The circuit of Assen is the only circuit outside the UK which boasts the title of TT, as its first meetings were held on public roads for over 28 kilometres: from 1955 it has taken place on the track which is still used, with the exception of the straight section which takes place on a public road and is therefore easily usable by ordinary people. In 1992, local governors decided to permanently close the track and give it over to the exclusive use of the competitions, following serious accidents owing to illegal races that were held on the side open to the public: the northern section has been being modernised- not without numerous controversies - since 2005, with the replacement of fast corners and the construction of an entertainment area and new stands. 
The first race held at the renovated Assen circuit, in September 2006, was won by Britain's Chris Walker (PSG-1 Kawasaki Corse) who was almost five seconds ahead of Andrew Pitt (Yamaha Motor Italy WSB) and more than 24 seconds ahead of Michel Fabrizio ( DFXTreme). The Australian Pitt stepped onto the podium in race-2, with the second place going to Troy Bayliss (Ducati Xerox) - then crowned World Champion at the end of the season - and ahead of Fonsi Nieto (PSG-1 Kawasaki Corse 2).
