I have has my Bandit 1200 at the racetrack, I hit an indicated 240km/h, and she was still pulling strong!!! I am pretty big, and it was hard to get right under the screen, but it makes a huge difference at those speeds!!!

I have had my 04 1200s up to 150 on the speedo, but thats with a slip on , airbox mods and a rejet.. and at that speed it was still pulling pretty good... had to back off.. could just hear an officer saying" what in gods name were you doing 160 miles an hour for, ya got a death wish???"... have to find a track to get my top speed..LOL

If you got pulled over with the speedo reading 150mph and you have stock gearing, the officer would more likely be saying, "What in God's name were you doing 135 miles an hour for? Got a death wish?"

This is a caculation using stock gearing, 15/45 and a tire circunference of 77.875". You will note that 10,500 is 180 mph. I have used this chart for many years, and it is right on. 9,500 rpms is 163. The GSXR 1100, has the same gear ratios as the Bandit 1200.

I took mine on a local motorway which is never very busy and got it a little over 160mph on the clock and the throttle wasn't even full on the stop it has been jetted and has an after market can, stock gearing,
i know the speedo's are a little on the optomistic side but still nice to see the needle on the 160 mark.

Quickly dipped the speedo to 153 last weekend, and it was still pulling pretty hard.

I traveled for a week with a GPS and found that I was about 8-10% off at any speed

...so who knows

Bought my '97 B12 on Saturday, took it out on Sunday to get the oil warmed up ready for an oil change, but the weather was really good so stayed out for a bit longer than I'd planned....

It ran to an indicated 145 at 9000rpm (on a private test track!). Haven't even checked the gearing yet.

As we all know, motorcycle speedos are error prone, and unless you put it thru a radar gun, preferably one not held by a State Trooper, its guesswork. I don't see an aerodynamic brick like the B12 going past 145mph without some serious help.

If I remember correctly, early GSXR1100's were magazine tested by radar in the 140-145mph range. Granted that was a 1052cc motor, but those bikes were a good bit more streamlined than the B12. Early 90's factory Superbikes were struggling to hit 160 at Datona. These were 390lb fully pumped up, streamlined factory machines geared for a high speed track like Daytona.

As speed increases parasite drag increases at a disproportinal rate. Without streamlining, it becomes a battle, with large power increases required for small gains in speed. Anyway, it is just a number.

The early-type (pre '02?) Bandits have speedo's and rev counters that are about 10% optimistic. This has been verified by a number of very reliable sources.

Hence, my indicated 145mph at 9000rpm is in reality about 130mph at 8100rpm.

I have a GPS on my Bandit and a dyna shift light and you are right, the speedo and the tach are off about the same. I can set my shift light for 6000 rpms, (it's lowest setting), and when it comes on the tach will be past 6500, and when my speedo is at 60 mph, my GPS is at 55.

An interesting little experiment today - after a couple of goes it ran to an indicated 9200rpm in 5th gear, but when I tried maxing it out in 4th gear it ran to exactly the same speed (and was still pulling) at an indicated 10500rpm...but after all that I do realise that Bandits aren't about top speed!:roll:

It does feel slightly overgeared with a 45t back sprocket, and I realise now why so many people go to a 14t front sprocket or 47t at the back. Personally I think 47t at the back is the way to go for best all round performance on a B12 (with the usual loud can).

Hi

I had my 1997 Bandit on an airfield for top speed runs a couple of months ago.

Best run was 166.2mph (with the speedo needle somewhere around where 180mph would be if marked that high). This is on standard gearing and was 600~700rpm into the red in top. On all the runs the speedo was about 10% over.

The bike is not standard (Akrapovic, 1216cc, skimmed and ported head, reprofiled cams, K&N filter with the lid chopped off the airbox).

Video of a slower run is here (bullet camera taped to the top of a tank bag):-

Note it is about 55mb.

All the best
