motorcarspec.com – Honda CBR1000RR-R Fireblade has a new top end, including a swap to finger followers and DLC (Diamond Like Coating) cams, which reduces friction and improves durability. There is also a clever new patent-pending semi-cam gear train, which is just code for ‘shorter cam chain’.
The bottom end has been worked over too. The con-rods are now forged from a titanium alloy, the small ends are coated with Beryllium copper and the piston skirts are Teflon-coated.
All of this reduces friction, allowing Honda to rev the engine like mad and achieve the big power figures they’ve clearly been chasing for track success – it’s got a whopping 26bhp more than the outgoing model.
This obviously hasn’t been without its difficulties – the new engine has an intricate cooling system to prevent bore distortion while at high rpm the pistons are sprayed with oil to cool them down.

A new exhaust features a silencer made by Akrapovic, which has been designed with a load of funky valves and pipe work. These not only push it through Euro5 without too much kicking and screaming but also help reduce the size of it by a third. Having said that, overall wet weight is up from 195kg to 201kg and some of that could be down to the extra catalysts in the exhaust.
