HONDA CBR1100XX TURBO

Let me start by saying that a stock Blackbird is already a great motorcycle. It's agile, comfortable, good looking and very powerful, one of the best all round bikes I've ridden. It'll tour, scratch or do a track day just as easily as it will take you to work and back.

A standard Blackbird features many of Honda's most innovative technologies, all integrated into a sleekly aerodynamic powerhouse, the CBR1100XX Super Blackbird projects an unmistakable image of a high performance machine that starts at its bullet-shaped nose and rockets through to its aerodynamic tail. The Blackbird is a seamless union of power, performance, comfort and practicality, combined with a hunger for devouring kilometer after kilometer of biking nirvana. Add to this an intercooled turbo... and you have all the attributes of the former, but with more than double the power.

The only big disadvantage of the horizon-bending turbo is that the fuel consumption goes for a ball. On a standard Blackbird I could easily ride from Johannesburg to Parys and back on a tank of juice, even at speed. Whereas, on Jack's beast I used four tanks there and back... thirsty hey. And it's almost impossible to ride slow, although I had to ride OFF boost for about ten Ks on the way back, otherwise I wouldn't have made the Blockhouse petrol stop.

Riding Jack's bomber was such a thrill, especially when the turbo comes in. The compression ratio has been lowered from 11.0 : 1 to 9.5 : 1, so there's a bit less power under 4000rpm, then you feel and hear the turbo start spinning at around 5000rpm (at which point you're doing 180kph), then as you zip past 200kph (6000rpm) the turbo really starts boosting, and all hell breaks lose. It's like... FUUUCK, HANG ON... Everything changes, the bike just takes off, it's like accelerating away in second gear. The speed just builds and builds, reaching over 300kph (on the clocks) is so easy.

When pulling off in First you have to feed the power in real slow, or it'll just flip. Second is slightly better, but still you have to exercise great restraint with the throttle or the front wheel will be in the air. Third-gear and it's still a battle to keep the front end down, it's only when you get past fourth that you can grab hands-full of power and then you need to make sure you have a clear road ahead of you... it all happens so fast.

This is one very strong, road-legal motorcycle, the power is truly AWESOME!   OH, and it handles great as well.

Advantages: Ultra smooth, ultra ultra quick!
Disadvantages: errr... fuel consumption?

nice 'n clean looking without any pipes

Sorry... couldn't get a photo of the clocks at these kinda speeds,

so pictures of GPS true-speed readings will have to suffice.
