I met the owner of this Honda CG 125 tricycle when it still had the stock fuel tank and chain-drive. Besides adapting the tank of the Honda CB 400 from the '80s, in the meantime it had also been converted to shaft-drive.
Enabling the coupling of a driveshaft to the secondary drive is an auxiliary gearbox that not only turns the sense of rotation in a 90-degree angle but also provides reversing. It's a common feature in many Chinese tricycles, but only recently it became more widespread in Brazilian conversions.
Originally converted by a company that is now defunct, it was basically rebuilt by its owner who made an entirely new rear subframe suitable to the fitment of an Asia Motors Towner/Daihatsu HiJet rear axle which also had to be narrowed and having the differential pumpkin relocated closer to the left edge of the axle in order to be properly alligned with the driveshaft.
Final drive ratio is now lower than what was used when it still relied on chain-drive, decreasing the top speed, but for a strictly urban usage on short distances it's still suitable.
Motor industry in Brazil used to follow a slower evolutionary path compared to its counterparts, which reflected in some older designs retaining a longer production cycle locally. A good example is the Chevrolet Advanced Design truck series, phased out in the United States in '55 when the Task Force series was introduced. Even though the Task Force had been available in Brazil through imports, the production of Chevrolet trucks in Brazil started with the Advanced Design and a local restyling to keep its appearance more up-to-date with the foreign models. Both the original Advanced Design and its Brazilian facelift featured here were at an old car show, with the "Chevrolet Brasil" mildly customized even though it retains most of its basic design making it easily recognisable. The taller front fenders and the engine hood wider at the front edge do lead its cowl to resemble more the Task Force, but the cabin is undeniably the same of the Advanced Design series.
The pick-up box retains more of the original style of the American model, with less curves on the rear fenders being the most noticeable difference.
