Yoshimura introduces 2025 Honda CB1000 Hornet SP AT2 Slip-on

CHINO, CA – October 30, 2025 – (Motor Sports NewsWire) – Our AT2 Street Series slip-on is just what the brand new Honda CB1000 Hornet SP was asking for. At last the AT2 is here to enhance an already stunning naked liter machine!

Now the big Hornet sounds mean and has extra ponies to boot with the AT2 slip-on, and nothing beats the sound performance and looks of the AT2.

The Honda 1000cc inline 4 engine responded to our Street Series AT2 with a resounding YES! This slip-on provides more power and torque across the entire spectrum! Power gains are up to 4.2% more HP @10,000 rpm and up to 3% more torque @9,600 rpm, and it doesn’t stop there. Our slip-on with a custom carbon fiber heal guard helps the new CB1000 Hornet SP loose a substantial amount of weight, 6.7 lbs! That over half the weight from stock. The exhaust note that our AT2 produces is second to none!

Yoshimura’s AT2 is designed, developed and manufactured in Chino California.

AT2 matte carbon end cap and heal guard accentuates the lines of the 2025 Honda CB1000 Hornet SP.
