Once a year, cars are banished from the Killarney circuit north of Cape Town and the two-wheeled brigade have the track to themselves - and immediately a number of good things happen.
Firstly and most importantly, there's no oil on the circuit. Look, we're not accusing anybody of malice here but history tells us that in 99 percent of cases the cars drop the oil and the bikes crash on it.
Secondly, there's enough time to run a two-hour endurance race - the only one on the Cape calendar for full-sized motorcycles. With three compulsory rider changes (even if you're riding solo, you have to take three two-minute breaks) it's the only time Cape Town petrolheads get to see motorcycles making pit-stops.
The Two-Hour is open to anybody (professionals, amateurs, mixed teams with one of each or solo riders) on any type of motorcycle of 400cc or bigger, although the demands of the bumpy, old-fashioned circuit put 600cc Supersports machines at a distinct advantage. Expect the top riders to complete more than 80 laps in 114 minutes of riding at near-sprint pace, with tension and lots of drama throughout the field.
Then there's the Breakfast Run Grand Prix, a fancy name for a run-wot-ya-brung contest for wannabe racers who've not held a racing licence before. It has a very real purpose: to discover new talent among riders who haven't previously thought of themselves as potential racers, and every year there are at least a couple of scary-fast amateurs to surprise you - and themselves! - with how fast it is possible to go on a streetbike.
Reigning Class B Superbike champion Shakir 'Shrek' Smith made his racing debut in a Breakfast Run Grand Prix.
The Ladies Race is always interesting - and not only for the pleasure of watching personable young ladies in tight leather clothing. Women in general lack the upper-body strength of the male riders and are less able to force the bike to go where they want it to, so they have ride the bike rather than shove it into corners.
The result is a smooth, classic riding style with high mid-corner speeds and sweet, almost finicky overtaking moves. Watch and learn.
The Honda CBR150 class is usually run on the half-main, which has no straights to speak of. On the full circuit the little singles run nearly 800m flat out down the main and back straights and, since they are all mechanically identical, they all run together, sounding for all the world like a Second World War bombing raid.
The 150s always deliver the closest racing of the day, with finishes often decided by hundredths rather than tenths of a second.
The Battle of the Twins can be something of a mixed bag, as big, booming Ducati and Aprilia superbikes take on the incredibly sweet-handling BMW F800 parallel twins, with the occasional Aprilia Supermotard thrown in for good measure - but it's worth watching just for the sound track!
For sheer, flat-out speed, there will be two Superbike races, while the Classic and Vintage Superbike racers will, as always share the circuit with the nerveless teenagers of the Powersport class.
There will action on the circuit all day at the Biketique All Bike Race Day on Saturday January 28, with qualifying starting at 8am and the Two-Hour, the last race of the day, ending at 5pm.
