#190 SR400Custom Report
We have been gradually customizing an SR400, inherited from the previous owner’s mother, for a distant customer over a long period of time, each time we take it in for inspection. This time, we finally got closer to the owner’s ideal form, so we uploaded it to this custom gallery. It’s a compact chopper with a short garter fork at the front and a hardtail at the rear.

Custom List
FrontHandlebars, F forks, headlights, etc.
【Front Fork】
◯The front fork is a one-off short garter fork made at another store. We remade the upper and lower shackles and readjusted the trail width to improve the dangerous handling due to negative trail and to secure ground clearance.
【Front Tire】
◯ A classic watermelon pattern, a vintage style tire with height.
【Headlight】
“5.75 inch Bates Light Black General Purpose“
〇A classic headlight with a size that suits the SR400/500 vehicle class well. Black.
【Handle/Handle Area】
◯The handle is a one-off at 2%ER. It’s a riser-less drag bar made compact to match the atmosphere of the garter fork, finished in powder black.
“Amal type throttle holder, general purpose (for 7/8″)“
◯The handle area, controls, meter, ignition-related parts are all neatly processed in the standard 2%ER style.
〇It is newly installed by welding to the lower part of the stem, which is inconspicuous and easy to operate.
“MOTOR ROCK Decompression lever“
A decompression lever directly attached to the engine to simplify the area around the handle.
【Front Blinker】
〇A standard small bullet blinker, black. It is a 10mm diameter mount.

CenterTank, oil tank, seat, step, muffler etc.
【Muffler】
◯Because the body of the car has become too low with the short garter fork, we have been using the fishtail end that we had installed before to create a one-off shotgun style exhaust pipe. We have ensured the minimum ground clearance.
【Seat】
“BATES Type Genuine Leather Solo Saddle Seat Vertical Tuck Roll Black/White“
〇A genuine leather solo saddle seat with a balanced price, look, and comfort. It is installed with a soft ride that is hard to bottom out by changing the mounting angle and spring input position.

【Gasoline Tank Installation】
“Sportster Tank”
“Welding nut non-through M8 2p“

〇Enlarge the hole diameter and change to a rubber mount specification to hold the non-penetrating nut. Used on both sides.
“Weld tab L size 4.5mm thick steel 2p“

【Hardtail】
『“Rigid Line” Bolt-On Hardtail Kit』(13cm long, made to order)
〇As the name suggests, this is a detachable hardtail kit using bolts/nuts. It remodels the seat rail of the original frame to make it a rigid line. You can revert to a swing arm/rear shock specification when you need to pass an inspection or change the style.
【Rear Tire】
〇The rear wheel is a standard 18-inch, with a vintage style, watermelon pattern classical tire selected.
【Rear Fender/Tail Lamp】
◯The rear fender was installed by cutting the side part of the Fat Bob fender that had been installed previously. A deadstock mud flap was modified and attached to the front part that was slightly short, reducing the cost of creating a new rear fender.
◯We installed a “Lucas L525 Replica Tail” inside the rear fender.
