Abstract: A tyre 1 for a motorcycle comprises a tread portion 2 and a pair of sidewall portions 3 connected with both ends of the tread portion 2 and extending inwardly in a tyre radial direction. A connecting portion 9 of the tread portion 2 and at least one of the pair of the sidewall portions 3 is provided with a plurality of protruding portions 10 each protruding outwardly in a tyre axial direction. The plurality of the protruding portions 10 is arranged in a tyre circumferential direction with a space 11 between each other.

Abstract: In a tire 2, a band 12 is disposed between a tread 4 and a carcass 10 in a radial direction, and is layered over the carcass 10. A first carcass ply 30 of the carcass 10 has a main portion 30a and turned-up portions 30b. A second carcass ply 32 of the carcass 10 is disposed outward of the main portion 30a of the first carcass ply 30 in the radial direction, and is extended on and between one of the beads 8 and the other of the beads 8. Ends P2 of the second carcass ply 32 are disposed between the beads 8 and the turned-up portions 30b, respectively, on outer side in the axial direction. Ends P1 of the turned-up portions 30b are disposed between the main portion 30a and the band 12. The turned-up portions 30b and the band 12 are layered over each other.

Abstract: A motorcycle tire includes a tread portion including a central region and a pair of shoulder regions. In a cross-sectional view of the tire under a standard condition, the central region has an outer profile protruding radially outwardly and having a first radius of curvature R1, and each shoulder region having an outer profile protruding radially outwardly and having a second radius of curvature R2 smaller than the first radius of curvature R1. The tread portion is provided with a zigzag central main groove in the central region with zigzag corners, a plurality of shoulder lateral grooves each extending axially outwardly from each zigzag corner to one of the shoulder regions, and a plurality of shoulder sub groove each disposed between a pair of circumferentially adjacent shoulder lateral grooves and each extending axially outwardly from the central region to the shoulder region.

Abstract: To provide a cell balance circuit and a cell balance apparatus with a low cost and with a compact size, and configured to equalize the charge voltages of rechargeable batteries when the rechargeable batteries are charged or discharged, while suppressing deterioration of the rechargeable batteries. A cell balance circuit AA includes a transformer T, a switch SW1 arranged so as to form a set with a rechargeable battery BT1, and a switch SW2 arranged so as to form a set with a rechargeable battery BT2. The transformer T includes a primary winding Wa arranged so as to form a set with the rechargeable battery BT1, and a secondary winding Wb arranged so as to form a set with the rechargeable battery BT2. When the rechargeable batteries BT1 and BT2 are charged or discharged, the cell balance circuit AA synchronously controls the switches SW1 and SW2.
