High-performance exhausts for new CBR 650R


Italian exhaust manufacturer MIVV has been designing and manufacturing exhaust systems for the motorcycle sector for over fifty years. Among its latest news are additions to the range of aftermarket exhausts for Honda's 'CBR' family - with some new complete systems that are designed to highlight the sporty style of the latest (2024-2025) 650R edition. 

Track-only MK3

The manufacturer guarantees full regulatory compliance for street legal riding but has also added to their 'package' of refinements developed exclusively for the track. 

MIVV first developed exhausts for the CBR in 1991 (for the 600F) and have therefore designed exhausts for all the different engine platforms that have carried 'CBR' sub-branding since then - singles, twins and 4-cylinders. 

For the current 2024-2025 CBR 650R MIVV has focused on three complete systems, two of which have MIVV manufactured catalysts. The third system is the track use version. The silencers used are the AK-1, GP PRO and the MK3 - each offered in two finishes. 

AK-1


The AK-1 silencer is produced with a stainless steel or titanium body, with both versions using a carbon end cap with a twill weave. It is an extremely light high-performance system, and a carbon heat shield is supplied. 

MIVV quotes max power of +8.60 hp at 11,600 rpm, max torque +6.60 Nm at 9,500 rpm and weight of 2.7 kg (-2.9 kg with the Titanium silencer), with the constant power gain rolling on at around 3,000 rpm.

The GP PRO exhaust has a compact, business-like design developed with semi-artisan TIG welding. The exhaust outlet pipe is equipped with a removable protective grille that hides the dB-killer.

It is available with a silencer featuring a central carbon body with a glossy finish; alternatively, there is the black stainless-steel version – which uses a special painting process. A carbon heat shield is supplied.

Max power gain is +8.50 hp at 11,600 rpm, with max torque at +6.60 Nm at 9,400 rpm and a -2.6 kg weight reduction.

GP PRO


The track-only MK3 line is the result of the experience gained by MIVV in the Moto3 and Moto2 World Championships. The system can be chosen with a silencer produced with a central body in glossy carbon or in black painted 304 stainless steel – features include the protective grille on the gas outlet bottom. A carbon heat shield is supplied.                                              

The Max power is put at +7.90 hp at 11,600 rpm, with Max torque of +5.90 Nm at 9,500 rpm and -3.5 kg weight saving.
