Small size motorcycle, great performance of my Sundown Hunter 90
I couldn't avoid the call of adventure. I decided to go to Chapadão do Céu - GO and get to know the region. In this way I would complete the break-in of my motorcycle's engine, and I could test the bike in unpaved rural roads.
What I couldn't foresee at all was the treacherous state of the roads I would ride in. The Brazilian roads in general (federal, state and local roads) are needing maintenance badly . In reality some of them deserve to be rebuilt.
On the 19/07/2007 I left Goiania - GO by 08:30 hs heading southeast. Up to Rio Verde - GO I rode on a federal road BR - 060 which has plenty of bogs and patches at the tarmac. From Rio Verde up to Jatai - GO the road surface is a little bit better. Generally speaking I could say that the roads I travelled in are deserving attention from the authorities encharged of their maintenance and conservation.
My Hunter 90 performed very well indeed, and I could achieve an average of 45 km/litre of fuel in the first stretch of the trip. I took advantage of the absence of frontal winds, and ocasionally I was benefitted by the lateral or back winds which contributed for the good performance of my bike.
After Jatai - GO I headed to a crossroads located after the petrol station Estrela Dalva, where I took the gravel road to Chapadao do Ceu - GO. This road is 122 km long, from which only the last 42 km are paved. During the first 22 km my Hunter 90 began to show its real value in a unpaved and dusty stretch of road with loose small sized gravel.

The road became worse and worse, the big plains became ups and downs, the gravel became loose stones, and to complete the picture there were many big sandy bogs and lateral erosion holes calling for my constant attention. I realized that even a trail bike would have to be conducted carefully on that road. I put all my riding experience to work in my favour in order to safely complete my journey.
Surprisingly my little Hunter 90 overcame all the obstacles, hindrances and perils and I could keep myself mounted, as if I had been riding a wild mustang. The suspension worked superbly, and the bike proved to be very sturdy indeed.
After completing this mentioned stretch of road, the worst that I have been riding in so far - about 62 km long - I could confirm how valiant this little motorcycle is. We escaped unharmed from all obstacles, thanks to the very well devised project of this bike. I had to change gears all the time in order to have the engine with enough power to surpass the bogs, loose sand and gravel, at this bumpy and stoney part of the road.
When I reached the tarmac again I could enjoy riding 42 km to finally reach my first destination: Chapadao do Ceu - GO. Along this stretch of road I crossed with four vehicles only (two small cars and two light trucks), and I was priviledged to see many wild animals at the road sideways or even crossing the road in front of me (foxes, seriemas, emas, a sunbathing snake, many birds and a beautiful deer).

I spent the night and the following day at this town. I took some photos and took a rest on Friday (20/07/07). On Saturday morning I left the hotel heading to the state of Mato Grosso do Sul - more precisely to Chapadao do Sul. Chapadão do Sul - MS is a kind of twin town of Chapadao do Ceu - GO - located 52 km apart from that; they share a common origin and their main economic activity is agriculture. Despite the similarities the city belonging to Mato Grosso do Sul has developed better than its sister town in Goias, due to better roads.

From Chapado do Sul to Cassilandia - MS I could ride in a good road. At Cassilandia I diverted to a secondary road that took me back to the state of Goias where I crossed through some small towns: Itaja, Itaruma, Caçu, and t hen heading to Rio Verde - GO. I planned to spend the night at Rio Verde - GO in order to meet my friend Itajara do Carmo Cunha and family. Itajara was my mate in a memorable trip we did to the south of Brazil at the beginning of 1980. On that occasion we were on 125cc bikes, I rode my Honda ML 125 cc and Itajara rode his Yamaha RS 125 cc in a trip that we clocked approximately 6.000 km.
The road between Itaja and Itaruma really is in very bad condition, the very thin layer of asphalt disappeared. Last year this road was closed following an inspection by the state authorities. But due to the lack of other options they had to open the road to traffic again, and they are slowly taking steps to fix the problem. From Chapadao do Ceu - GO to Itaruma - GO I clocked 225 km and my bike spent 5,75 litre of gasoline, which resulted in an average of 39,13 km per litre. From Itaruma to Rio Verde - GO I achieved an average of 38,15 km/litre, and at the final leg of my trip between Rio Verde - GO and Goiania - GO I could get 40,9 km per litre of fuel.

On Sunday, 22/07/2007 - I was back to my home city of Goiania - GO after riding 1.100 km in three and a half days. My Sundown Hunter 90 performed very well indeed, specially along the bumpy and stoney roads I rode in. My experience of 37 Years of Motorcycling allowed me to get the most from this little motorcycle. Considering the 500 km completed during the first day of my trip - from Goiania to Chapadao do Ceu - GO - in nine and a half hours (including there forty minutes spent on lunch time, and three ten minute stops) resulted in a considerable average speed; taking in account the small size and power of my bike.

About my Sundown Hunter 90 performance: I could reach 90 km/h revving at about 7.200 rpm; and I could reach speeds of 100 km/h revving at 8.500 rpm in stretches of road going downhill. This shows that the fourth gear of my bike has a very good overdrive ratio. It is interesting to mention that my weight is about 58 kilogramme, which added to my luggage totalled about 73 kg.
When using second and third gears frequently in the worst stretches of road I could get an average consumption between 35 and 38 km/litre, otherwise the average consumption of my bike situated around the 40 km/litre mark.
On the 23/07/2007 I took my bike to the Sunwdown dealer for the 3.000 km maintenance service. I decided to have the engine oil changed as well, due to the fact that I rode in many dusty roads. I did it before the 3.000 km recommended interval considering that I had changed it at the 1.000 km maintenance service. I always prefer to be at the safe side regarding my motorcycle's maintenance. I use the oil recommended by the factory (Castrol 4T 20W50 API SG Actevo).
During the above mentioned trip I noticed that the engine "gasped" when cutting the acceleration for a while and accelerating again, mainly in high revvs. I transmitted exactly what I had noticed to the mechanic Biagi of Moto Limongi - Sundown dealer where I bought my Hunter 90. Due to his expertise he could adjust perfectly the engine´s carburation, which resulted in the ideal mixture of gasoline and air.
On the 17/08/2007 I refuelled my Hunter 90 after riding for 357 km in urban traffic. I topped up the fuel, utilizing 7,61 litre of additivated gasoline. I became extremely happy due to the average consumption achieved by my Hunter 90: 46,91 km per litre of fuel, riding in urban traffic only. Now I am sure of reaching my personal target: more than 50 km/litre when riding on roads.
Next day (18/08/2007) I went to the city of Goias (World Heritage city, due to its preserved colonial infrastructure) with my Hunter 90. I rode for about 304 km (two way) spending 6,92 litre of fuel, which resulted in an average consumption of 43,93 km/litre. I must highlight that I left Goiania - GO by 09:30 hs and I returned by 13:30 hs.

The weather was hot and dry, and added to that I accelerated the bike to speeds of 90 km/h (at 7.800 rpm) and up to 100 km/h (at 8.200 rpm) in some stretches of road going downhill.

On the 27/09/2007 I topped up the fuel on my Hunter 90 and what I observed then made very happy indeed: my bike had covered 337,6 km on 6,74 litre of gasoline, which resulted in a superb average consumption of 50,08 km/litre on urban traffic. I finally reached my initial target according to my first estimate for this bike.

So, in my opinion, the Sundown Hunter 90 is essencially a small motorcycle geared towards urban traffic to be ridden according to the flow of vehicles, preferably at low and medium speeds. But in spite of that I have been testing it on roads. Taking in consideration its small size and power output I am surprised by what I have achieved with it so far.
It is worth mentioning that this little motorcycle has an excellent performance on dirt roads - either during dry weather or wet weather.
