#267 SR400Custom Report
We received an order from Aomori Prefecture and based on the “Bobber/Compact Chopper Complete“, we created a SR400 in a chop cafe style with a separate handle. The base is a 2008 model, and we cancelled the immobilizer that would interfere with the simple custom style, and significantly reduced various harnesses while producing it.
By extending the swing arm by 3cm and dropping the frame under the seat, the seat position is lowered, which has the same effect as raising the handle, significantly improving the forward-leaning posture of the separate handle that usually puts a lot of strain on the upper body, palms, and arms. Combined with the mid-high step that can distribute body weight, you can ride in a more comfortable position than you might imagine.
The overall style is a compact exterior with thick feet, and we have balanced each of the owner’s specified items. Even if you change to an up handle for a change of mood, it is finished in a silhouette with a sense of unity.
