Re-tuned CBF1000 engine

I have been reading that the 2008 CBF1000 engine is a "de-tuned" CBR1000RR... so here is the $1M question: what do you have to do to "re-tune" it to bring back some of the loss power/torque?

Knowing Honda, there's a lot more to it than bolting on the CBR1000 parts such as cams and maybe pistons. I'd be willing to bet the ports, valves, throttle bodies, and exhaust headers are smaller, and the pistons, rods and crankshaft are "less expensive" pieces for whatever reason. Let us not forget the lighter valve springs, radically different ignition curve, completely different fuel delivery maps and rev limiter settings, smaller injectors, and ... well, let's just say the dozens of little things that in combination convert a relatively cammy firebreather into a midrange monster would have to be unengineered, and the end result would be a wahoo!!! in a straight line, but an absolute beast to get to the other side of a corner at any kind of speed with the rider still connected to it. In other words, an archtypical Florida bike.
Go for it! Just make sure your insurance is paid up and your will is up to date.
Of course, you could always convert a recent used CBR1000 to a naked (I've seen several) and still have the razor sharp handling that much horsepower absolutely requires. It would probably cost a lot less in the bargain. There are currently 26 listed on EBAY for a median price of $6,350, and a 2000 Aprilia RSV1000 for a Buy it Now price of $2,800.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Why do you ask, are you buying a new CBF?

No way it's making only 114. It's supposed to stomp the FZ1 and S3.

My guess would be 130-140.

Mister B tell us the story of your test flight/ride on the CBF1000, it's a good distance to Canada from here in Charleston, SC just for a test ride.
Now let them fingers do the talking!

Don't forget, we are talking about the CBF1000, not the CBR1000RR.

i'd read similar, low output figures. that was sure a long way to go to get 10 hp and 6 lb/ft of torque over our beloved 919's...

Dear Honda: naked means no bodywork, it's not meant to describe the dyno charts.

Here are my first impressions after riding a 2008 CBF1000 for 15 min; ps: I intend to take it for a more extended ride.
- Very comfy seat and riding position, a bit more straight up than the 919; the suspension is much more forgiving over "pot holes" but have not tried the bike one curvy road. However very good torque over all the range (it seems beeter thatn the 919) but maybe it was only the exhilaration of trying the new bike??
- I t amazing how smooth the shifting and hard acceleration (straight line) is.
- Very good breaking. Though, however I have not engaged the ABS.
- The wind screen has two manually adjusted height; on the lowest position there was no more no less that the Givi A276 screen.,, I am planning to have it adjusted to its highest position (~1.5in higher) when I take for a "longer ride". PS: The bike seating height can be adjusted +/_ 15 mm or +/- 5/8”.
-Good grunty sound form the exhaust pipes.. but I did not take care too much for the shape or finish (one up for the 919).
- All and all very enjoyable first ride...
PS: comes only in 2 colors tough black or silver metallic.

The retail price is Canada is $11,999.00; so how many do we already have for a group buy?


'02 919 and I love it.... but the CBF1000 is turning my head; decision, decision!

I rode a CBF1000 back in 2006, and compared it with the FZ1 (took both out from the dealers together), see 1000 cc Roadsters

I was also to some extent comparing with the Hornet 900 (919) and '03 R1 that I had at the time. Personally I couldn't find enough to like on the CBF1000 over my Hornet 900. It was incredibly competent, but just didn't excite me enough.

I am pretty much at that point... does not offer enough to trade the 919.

thanks all for the feedback!

I have a feeling some of the guys here are getting the CBF and the CB1000R mixed up. Not to mention the CBR1000RR..... 3 totally different bikes.
