* Ariel 500: In the final episode of Steve Wilson's epic African adventure, his Ariel single suffers some punctures but... gets there in the end

* Ariel Leader Rebuild: Part 10: Rod's back in action with a project bike that now runs. But the gearing's all wrong and the running isn't exactly right, either...

* 1925 BSA L25: Flat-tank heaven: this 2¾hp certainly looks as if it's 84 years old and is in 'wonderfully grubby' running condition. Back in the 1920s, this model conquered Mount Snowdon! Colin Sparrow tries his hand on a less terrifying test track

* 1971 BSA A65 Lightning: Maligned at the time, the 'too tall' 650 twin finds favour with Frank Westworth these days. He examines its strengths and weaknesses, takes one for a spin and considers the truth behind the bad reputation

* Moto Guzzi Le Mans MkV: Steve Bellamy adores the 1000cc Le Mans, which explains why he keeps buying them. Not so obvious why he keeps selling them, then, but he attempts to explains the mystique of the model

* 1971 Norton Commando Rebuild: The bike is now dismantled into Big Bits, but that means Matt has to struggle with all those components which just don't want to come apart. Where's the huge hammer gone?

* 1939 OEC 500: So unusual it's probably unique, this single-cylinder machine matches an AJS engine with Druid forks and OEC's own ahead-of-its-time swinging arm rear end. The owner tells its tale

* 1964 Triumph TRW 500: It saw many years in military service, and this sidevalve twin in a rigid chassis now offers a characterful (if mellow) ride. Rowena Hoseason looks at the history of the model and takes one for a ride
