Lets start with the moped. It has on it a standard 2,5 liter tank, and a maximum speed of 60km/h ... on a downhill. On the flat it will reach 55km/h, if the wind plays along. Basically what I'm saying is that she is not the most powerful bird out there. But I'm not complaining. For a 50cc engine, I don't think 55 is bad. In fact, when I bought it I was overjoyed!
If you do the math, it works out to a theoretical time of 2 hours and 12 minutes. If you cannot do the math, check out http://http://www.wolframalpha.com/input/?i=speed+distance+time&a=ListOrTimes_List So, in practice, I did not make the cut-off time. But I did come close. I estimate the journey to be around 2h30, which is not bad at all.
I knew the 2,5 liter tank would not last me 111km, so I planned to fill up in De Rust, which was 33km from Oudtshoorn, and then fill up again in Klaarstroom, 25km from De Rust. Then I would hold my thumbs and hope that the Red Devil would take me the last 52km. That seemed reasonable to me, as I have previously done 50km n a tank easily.
It did not work out exactly like this though. When I got to De Rust I discovered that I couldn't fill up with LRP (Lead Replacement Petrol). This was unfortunate, because I now had to do 78km on a single 2,5 liter tank! I eventually ended up running out of petrol 5km out of town! By then my dad had graciously brought me some petrol to get the last few kays.
I also miraculously only had one mechanical problem. This was when I ran out of petrol. Because I ran completely out of gas, there was no petrol to get the ped going from a kick-start. I tried bouncing it up and down, lying on its side, blowing into the tank, but eventually what got it going was when I removed the fuel pump and let petrol run straight into the filter.
As for the personal journey. It was epic. I got back pain after ten minutes of riding, there was hardly any space for cars, let-alone trucks to pass, the road was bumpy and often uncomfortable, and, I was caught in the rain for ten minutes! But I pushed on through. After everyone shared that they did not think me or my moped would make it, and after even I was having doubts, the venture was successful. By the time I had gotten to De Rust, I had decided that it was something I had to finish, and the feeling I got as I entered Prince Albert was awesome.
De Rust: Not much hope of getting LRP...
Would I spend another two and a half hours on an uncomfortable moped, battling with rain and an aching back? Definitely!
