Went on a nice ride today and took a detour over a summit to delay getting home to early, one of my favorite steep summits to ride. The first 5 kilometers has a passing lane and there were several large trucks in the slow lane. I got out in the passing lane and it seemed like I was never going to get by them all. I could see the sign indicating the passing lane was soon ending and there were still three more trucks to pass. I twisted the throttle and made it by easily. Looking down I was surprised to see I was travelling at 160 KPH which is 100 MPH. The bike was solid as a rock and I was surprised how relaxed my grip on the bars was. Good indication that the chest wind is very low, I have the tall wind shield. I got going that fast only once on my Harley and it was all I could do to hold on but it had no wind screen at all. The tall wind screen on the ctx is no where near as nice as the electric one on my old ST1300 but I have to say I was impressed how well it felt at that speed. I have put 2000 kilometers on mine now and have had it in the twistees a few times and the bike handles very well. :) Continue to be impressed and enjoy my new ride :smileygarden_de_ban

Sorry to say this: I'm too old for this!

190 km/h and something (hit almost the 200 km/h mark).:eek:

But absolutely stable!

When I hit the 170 km/h mark on my ST1300 (with installed top case) the thing started to swing (?).

So you pretty much maxed the top speed on the CTX1300, or really close anyway?
190km/h=118mph
200km/h=124+mph
I think the max is somewhere around 209km/h (130mph)

Good to know it's stable at that speed. I've heard of the ST1300 wobble at higher speeds but usually that was when slowing from high speeds. I guess I also heard about the wobble happening on the ST just going that fast. I'll never see those speeds, at least not on purpose. But good to know still. :)
Thanks for putting your life on the line and testing that :D

190 kph 'and something' sounds awfully close to 120 mph (193.1 kph, to be almost exact), which is what I believe the CTX1300 is electronically limited to. Even if it felt like it had more, which it very well may have if left untethered, I think you pretty much maxed it out.

Hey German Mike Thanks for posting your top speed, its nice to know our new bike is stable at those speeds. When I pass I like to get out and by fast and back in and that V4 can put your speed up there in a hurry and with its smoothness the speed creeps up on you. Sometimes you are up there un expectantly, I don't think anyone is going to top that speed..appreciate the info

yep, its a solid bike at speed, i have gotten one up to 125mph on a test ride and it was amazingly good even with the short windscreen.

Did you notice what the RPM was?

I still consider myself a newbie at this. I've just now started to feel almost comfortable on the freeway at 65mph/3500rpm.

Three days ago I reached the maximum speed (190 km/h) on the highway (178 km/h on my GPS) and the bike was all right but I know that 5 or 10 km/h more would have been too much and alas, this maximum speed is probably impossible - too dangerous - on a wet road (I didn't say when it's raining !). I feel insecure for the winter season coming. :(

No I did not notice the rpm, :350x700px-LL-66dd6d I have since hit 160 KM per hour a few times even 170 but did not notice the rpm. Next time I will and let you know...cheers Jim

Speed is almost, but not entirely, linear in 5th gear. At least very close to linear most of the way up the speed range.
All rpm are approximate only:
45 mph = 2500 rpm
50 mph = 2750 rpm
55 mph = 3000 rpm
60 mph = 3250 rpm (this is also specifically noted in some of the journalistic reviews)
65 mph = 3500 rpm
70 mph = 3750 rpm
75 mph = 4000 rpm
80 mph = 4250 rpm (as far as I've specifically noted, been faster but didn't look at rpm)
expect the rest to actually be a tad higher rpm than noted... maybe.
85 mph = 4500+ rpm
90 mph = 4750+ rpm
95 mph = 5000+ rpm
100 mph = 5250+ rpm
etc, etc...

I spend almost all my travels under 4000 rpm since I'm rarely on a road with a 75 mph speed limit. I like 50-60 mph best. Or 65 mph if needing to go some distance. No need to rush anywhere.

Best power range seems to be 2750-4750 rpm. And good power a little on either end of that.

Best mpg is between 2500 and 3500 rpm in 5th gear but still good mpg down to 2250 rpm and up to 3750 rpm. It starts dropping noticeably above that if watching the mpg meter.

going down a grade on a 75 north, I found that I was creeping up on 90! (in a 70 no less) and the bike was extremely stable.

This is why I miss the cruise control. I got out on the interstate today and I found myself going way too fast. I got off the four lane before I had a visit from the blue lights.

yep

Before I worked out a wind protection solution, I found the wind resistance from the shorty screen served as a sort of speed deterrent. I tended to settle in at 65mph and got slightly uncomfortable above 70.

No longer now that I have the tall screen + X-Creen installed! Intending to cruise at 65mph (in a 55 zone) on my commute this morning I found myself doing upwards of 85 two different times.

What's worse is my perception was first that the engine sound was different, then my eyes went to the tach and observed 4500rpm or so, and only THEN did I check my speed. It was THAT stable and quiet that I didn't really notice myself accelerate 20mph more than my intended speed.

Uh oh.

hi just for my own curiosity as its not meant to be a sports bike i managed 126mph on the clock, which was pretty good i thought, the 115 mph is easy then struggles, needs a long straight, but i dont recommend you break the 60/70 mph uk speed limits????? ride safe thanks Garry

Once when I had the short windscreen on I raced a guy on a new Harley and easily got a little over 120 MPH. But after installing the taller shield, I was on a long straight flat stretch of road so I decided to see what it would do. It got to 110 pretty easily but then struggled to get to 116 max. I was lying on the tank wit my feet on the rear pegs and there was absolutely no wind, but that is all she would do with the taller windscreen. Really disappointed.
I wonder if anyone will develop a chip or some other pipes for these things?

Just find a wrecked ST and swap motors? :tongue:

"a chip" alone will kill the engine. You would most likely need to do what the Venture people do: replace the camshafts with the ones from the ST1300 (and maybe the valve springs too) and then think about chip tuning.

Depends on what the chip is doing. There's usually a huge buffer between a factory tune and what an engine can dependably handle. That's especially true about this motor that was originally designed to put out a lot more hp at about 1500-2000 more RPM. There are minor mods that can be made electronically, particularly with fuel management, to enhance other bolt-ons like intake and exhaust. I think a lot could be done to this motor to tweak the output without coming close to blowing it up.

I wasn't talking "immediate catastrophic failure", rather "it needs an overhaul every 5 years instead of 20" :)

This is not meant to discourage people -- by all means, experiment and tweak it until you get it running like you want it, just keep yourself informed of the consequences and act in a knowledgeable manner at all times.

i know the ctx13 is no missile, but its got good legs around the a and b roads easy reaches the ton plus and will see off almost every other cruisers around the twisty bits, and if your a decent enough pilot can and mine has embarrassed some sports boys....alot of fun at manageable speeds, and with the handling and brakes to suit...basickly if you want warp speed buy a r1 or gsxr...i can ride this as fast as my last st1300, but its easier with it! ride safe cheers Garry
