815cc V-Twin Engine
For the machine, Yusuf made by his own the Kala Bendu's crankcase. The crankshaft and transmission containers are made from a mixture of metal waste. The material is from parts of unused machine blocks, which are then melted and reprinted for a new crankcase.
Engine blocks and cylinder heads uses the part of Bajaj Pulsar 200. Yusuf said it takes 4 blocks of Pulsar 200 cylinder. From four parts of the block then cut by him into 2 cylinders as the pistons place.
The piston rod uses the part of the old Norton with a stroke length of 100 mm, while the 72 mm in diameter piston taken from the Honda Excelent car. For camshaft, he uses custom cam. The degree and size of the sprinkler valve device was machined in accordance with the results of his calculations.

"The compression factor is low at 9:1, which is supposed to be ideal at 10:1, but I'll look for it later after this. Because with this size it has reached 120 km/h, if the timing belt that used is the part of Mitsubishi L300 petrol engine," he said.

In order to be safe and not hit by a lawsuit, Yusuf made his V-Twin engine with a 43-degree angle. This is because the 45-degree angle belongs to Harley-Davidson, while the Indians engine was 42 degrees.
Exterior
Not complete if the machine is made itself but the exterior is not. After completing the machine matters, then he switching to make the framework of a motorcycle. Where the frames itself is made of 30 mm diameter pipe and 6 mm thickness. The frame was combined with the Yamaha R15's front shock that has been modified with an additional oil tube.
There is something interesting here that is the form of rear suspension. Instead of monoshock installed, Yusuf rather uses two shock units that are made in a horizontal position. Those shock units were given an additional plate and connect to the middle of the rear arm made of 2 mm pipe box.

Because it using the rims that taken from the Honda CX500 which originally use axle, in here Yusuf was forced to re-create the rear wheel holder to be driven by the chain. Where the chain is connected with gearbox taken from the 1956 BSA 350.
While the gas tank is made of 1.2 mm drum plate and wasp tail from 2 mm plate. Finally as a sweetener, tank, wasp tail and upholstery then covered with genuine leather complete with special Javanese ethnic carvings of the puppet figures and mega mendung motifs made by Cetul Leather Art from Yogyakarta.
