    HA HA Hey Guys RPM.. at least on that crappy stock Suzuki Tach. I was amazed it revved like that but had a LONG Highway to do it on. I took it back in the eighties to the track, Im 240 plus, without any front lowering no struts or even letting air out of tire It ran 11.20 at 125 with my fat arse on it. This was a lowly 1000 Modified a Lot . 29 Smooth bores ported Head cams valves springs but stock valve diameter, lobe centre 110 degrees, manual cam chain Tensioner, welded crank and clutch ,, Oil Pump Gear mod. (750 ones) Undercut and welded Transmission gears. Stiffer clutch springs and copper plated steel plates also. That old 1000 was a nice Bike . Never should of sold it.

    On the Highway my Old Modded GS 1000 could easily turn 12,600 in 5th gear plus, (Usually too bust steering to watch it very closely) Stock gearing, the Speedo would be down at the Letter m in the mph thats on the speedometer so I figure 140 mile hour plus Easy.

    On a flat smooth road I got it close to 80 mph but then it started to get a bit wobbly so I let up. The motor still had plenty but there's something up in the steering or suspension.

    You might need to service the steering head & swing arm bearings,the front forks also.

    I think I saw test mags get 125-126. Mine has never seen an honest ton.

    I never felt as comfortable at speed on the 1150 as I did the FZ1 or the VF1000R. I had the GS up above 120 a few times, but had the VFR over 140 many times and the FZ above 150 many times. Both bikes felt better at those speeds than the GS did 20-30 mph lower.

    I'm confident my '84GSX1150e will hit it's max with no problem. I've added about 20 extra hp and lowered it's weight by 30-40lbs. My mechanic did carb tune and test run and said it did 200km/125mph easily. Factory recorded top speed was 145mph, I've no doubt it will match that and more once I add a big bore kit(8-10% hp) and change the sprockets for better highway cruising.

    Not that I have any intention of testing it's top end range, I've done that and don't feel the need to do that again. I'd like to keep my driving license.

    All I knew is that first gear was able to be shifted into, and I went for it lol.

    I was glad nothing else happened too! Surprised me alot but in a good way. I just remember how free the front end felt for that bit of a second and was like holy $%/# the front end came up!


    If the thing was manageable to wheelie which, that shows it might if I were to try to on purpose, I might try to learn if I feel comfortable. She sure is heavy though, even though I cant feel it riding....

    I saw the guy that bought my first streetbike - a Kawasaki LTD 550 do a wheelie. I was impressed... and surprised.

    Didnt expect it either. Again it was more of a hop up not a wheelie!
