Agreed. I was referring to the 1200 in the Bonneville and Bobber - both heavier bikes.

Speed Twin and Thruxton are a different class.

However. For $9k I have performance that I love and more like a more expensive bike.

I looked at a speed twin but it’s too tall for me. I am very short.

Additionally, if I get another bike, probably a street triple (LRH). Have a classic type and a sport modern.

Thank you for the distinction. I should have clarified.

I have 2000km on my Tec cam and did not expect as much satisfaction as this.
The bike runs super smoothly and as already stated I get to the red-line with ease.
I know have a nimble,nippy modern classic that likes to be thrown around our mountain roads here.
Thanks Tec!

Iím vertically challenged at 5í8 and they were able to sag the springs so that I can pretty much flat foot the Speed Twin now. It can then be lowered even further with aftermarket shocks.

Just sayiní, donít write the Speed off. Itís a hell of a fun bike to ride.

Understood. The Street Twin is my first bike. I race a Formula car, have a 700HP Porsche 911 Turbo, etc, but this is my first bike. I wanted to stay in a safe range for a beginner bike. Speed Twin seemed like a little much in addition to the height. I didn't upgrade the CAM to be a speed demon. However, the bike feels so much better now. I recommend it to anyone who doesn't want their 900 choking.

Having said all that, I would definitely consider a Speed Twin, especially if I can a) lower it and b) can only have one bike. I have taken to going on long rides and I am not sure the Street Triple will be as comfortable. If I get a second bike in the future, well, then, Street Triple would be cool. Again, still working my way up though.

I am 5'4" with short legs. Would have to lower it a bunch.

Talked to my dealer, and we decided to hold off on the cam for now. The bike is brand new, 3 weeks old, and installing the cam will void the warranty on the motor. He said it's better to wait till that first 10k valve check, which would probably be next year or so... by then I will have decided if I will keep the bike long term and the warranty will be more than half over, at least...

So we ordered up a new Brembo radial master cylinder from the Street Triple R and will fit that to help with stopping, a new black lever to match for the clutch, and I just ordered up the progressive spring and preload adjuster kit from TEC USA... Oh, and the X-Pipe. So it will breath a bit better, be a lot louder, stop better and handle better. I already have the Fox shocks on the rear, so the forks being stiffer will help.

It's a different bike....
I'll be interested in following how you get on with it.
With that in mind, has anybody experienced any issues post fitment? I've got one waiting in the sidelines for my '18 Street Scrambler.. Its only 6 months old and done 4700kms so I was thinking on waiting a little before I void my warranty..

I'll keep everyone in the loop.

Almost 400 miles on the the new cam and no issues. George has sold over 300 of these now. I'd imagine we would hear if there were major issues.

He was very clear about adjusting the valves properly. I think if you do that, and break the cam in properly, you should be ok.

Having said that, I understand now wanting to void the warranty. That seems like a personal preference though. For me, it's a different bike and was worth it. However, if something goes wrong, we will see what I say then, right?

Yeah, for me the bike is less than a month old, so nuking the motor's warranty that early on makes me hesitant. So I am just focusing on tires, brakes and suspension and maybe by the time I am due for the 10k valve check, I will be cool with giving up the remainder of the warranty... and at that point they will be in there checking and adjusting valves anyway...

I did it to my Scrambler and am very happy. But it still doesn't pull like the t 120. But it's close and as the 900 is more nimble it will push any 120 until the open road and the 6th gear comes into play.
Funny how everyone is lowering there to flatfoot, I'm going the other way and now can't flat foot 2. But 1 on the peg 1 on the ground is all that's really needed.

Agreed. I have done a cam in my 1200 thruxton. I found around 140km/h it seemed to slow down in the pulling.and just slowly built up speed after that.
Now it easily gets to 180 km/h and hits the cut off. Also had the bike wind up to 9k+ rpm on the dyno . No problems .
Bike loves to sit.around around 6-7 k rpm
