■ Charm of Moriwaki 'Monster'
1. Creative Silencer Shape Known as 'Monaka-kan'
The most prominent feature is the unique manufacturing process where two aluminum plates are precision-pressed into 3D shapes and joined together. The nickname comes from its resemblance to the process of making Japanese 'Monaka' wafers. The beautiful weld beads (scale patterns) by skilled craftsmen boast warmth and precision that machines cannot replicate.
2. Stainless Steel and 'Heat-resistant Black Coating'
The use of stainless steel provides excellent corrosion resistance and a profound exhaust sound. The unique heat-resistant paint maintains a high-quality texture, and the after-sales support is extensive, including a dedicated touch-up spray.
3. Balance of Serviceability and Practicality
While adopting a 4-1 collection system, the internal structure is optimized to balance low-to-mid range torque with high-rev exhilaration. Additionally, it is compatible with the center stand, ensuring ease of daily maintenance.
