Now on sale for the new model (JA65) CT125. (This product is exclusively for the new model (JA65) CT125 and cannot be used for the old model.) JA55 is this product. https://8ftweekend.com/products/oil-cooling-system-for-ct125
The difference from the conventional engine is that the oil passage is extended instead of branched. Therefore, there is almost no drop in oil pressure, and the reinforced oil pump that is required with the addition of an oil cooler in the conventional engine is no longer necessary (in the case of the stock engine).
