■Product Description
Enjoy torquey output performance not found in the stock model.

■Detailed Description
●e-Stage Bore Up Kit 143cc
This bore up kit changes the displacement from the stock 124cc to 143cc by changing the cylinder and piston.
By installing it simultaneously with the FI-CON TYPE-e (injection controller), it achieves torquey output characteristics different from the stock model.
The cylinder uses a steel cylinder similar to the stock one.
Silver painted. Uses a cast piston.
Bore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (stock).
The version without a sports camshaft is for those who already have only a sports camshaft installed and are upgrading to the e-Stage.

■Notes
※Image is for illustration purposes only. Includes products with different sizes and colors.
※Product design and specifications are subject to change without notice. Please understand.
※When installing the e-Stage Bore Up Kit, simultaneous installation of the FI-CON TYPE-e (injection controller) is required.
※Since the displacement will be 125cc or more, it cannot be ridden on public roads under a Class 2 moped registration. It is for competition use only.
※Use high-octane gasoline.
※The cylinder used in the e-Stage Bore Up Kit does not have an oil take-off boss. If you wish to take off oil to an oil cooler, we recommend installing SP Takegawa's Special Clutch Cover.
※Since installing SP Takegawa's high-compression piston kit significantly increases engine output and torque, the crankshaft will be subjected to increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft.
The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the flywheel side end of the crankshaft, thereby suppressing twisting and deflection.
※This product is made to order, so cancellations after ordering are not possible.
※Since this is a made-to-order product, delivery may take some time. Also, there may be cases of discontinuation or specification changes without prior notice. Please be aware of this beforehand.
