BEST bang for your BUCK...Dr. Pulley Sliders for your variator

I would'nt think so, i can't think of a reason why anything like this would stress thr tensioner.
These are pretty common things to do to any scooter (This is my second one with DR Pulley sliders) and there really is no downside to these, that's one of the reasons most scooters owners change these out.
1. Better low end acceleration
2. Better top end gearing
3. Longer life
The only downside really is cost of parts and labor. Some scooters are harder than others to get to the variator. This one is pretty easy.
It seems like the 28 gram ones are the sweet spot. My top speed appears unchanged at 110mph, but everywhere else the scooter feels faster, most noticeable in part throttle applications.
At wide open throttle the engine is louder as it is reving to a higher rpm that it did before due to the gearing change, that's where you get your better acceleration.
I choose not to do the sliding pieces (Even though I ordered those as well) mostly because they are not a direct fit, you have to file down the edges of the variator to make them fit and at that point the stock pieces would not go back in if you even needed or wanted to return to stock. I honestly can't see them making that much of a difference performance wise, possibly they may make the varitator more quiet, but I don't hear much noise from it anyways.
As I was telling elamofo, I am local to you guys and have all the tools to do the job. I don't charge anything, I am a person that likes modifying things as a hobby.
Let me know if you want my help

So do you feel the 28gram rollers help with the throttle lag from a dead stop? I have sliders in the Vespa GTS300 and they made a noticeable difference. I could careless about top speed as I really have no desire to go beyond 90mph. I just want a bit better responsiveness off the line. I'm happy with the power band once rolling.
I changed them out on my GTS and it was fairly simple with the clutch tool. I'll probably order the BMW tool and do it myself.
It does help somewhat with the throttle lag from a dead stop, but the transmission has to do a fair bit of slipping before the scooter starts to move, that's kinda the nature of the beast I guess..

Put in a Dr. Pulley HIT Clutch...CURED!

Huge improvement. My Tmax 500 walks away from a C600/650 with a set of 16.5gm Dr. Pulley Sliders and my mileage increased...
One of the reasons PTWs are a blast is the customization possibilities. Based on what we have heard about your Tmax and the customization you have done, why the heck would you go to a Beemer UMV? OK, maybe if you had done the same thing to a C600...But still, the Tmax is a great bike.

I've read of C600s that had all the mods done in Europe; Mallossi variator, HIT Clutch, sintered pads, free-flow exhaust, Tmax (!!!) injectors, air horns and filter box mods, all with a computer re-map.
It's an absolute BEAST!!! The only problem is, after the warrantee runs out, or is VOIDED by all the mods, will it hold together? The Tmaxes were fortunate enough to have all the weak spots exposed in racing circuits in Europe, i.e. inadequate oiling to one of the main bearings under hard loads. That was an easy fix, it now lasts forever.
That's what I'm waiting to hear/witness. Some substantive steps from BMW to upgrade/retro-engineer the C600 so that it LASTS as good as it LOOKS!

Isn't that Ducati this same concept?

I know some of u have these mods/upgrades done.As i'm not so patient with e waiting time,1 of e scooter shops here have e 30g sliders but i've read around that e 28g ones is e best bang for your buck.What i ultimately want is just better acceleration from e stock C650GT with minimal expenditure done as i'm not really after big gains.My question is,will a 28g differ a lot from e 30g in terms of acceleration?I've also noted these changes compared to stock.Would appreciate any advice anyone have on these... Thanks

Just needs to last until the Ducati scooter comes out
I wouldn't hold my breath on that...
I wouldn't bother with the 30 gram ones. If better acceleration is what your after the lighter the better. The heavier ones don't make you lose as much top speed, but that's not what most of us are after since the top speed in this thing is good. After installing the 28 gram ones the difference is subtle, its not earth shattering. I would imagine the 30 gram ones would be even less noticeable.

700cc in the 90HP range. yup, i'd buy that for a dollar..
My only complaint with the C600 is the lack of power/torque.
If this thing has good storage and power im in...
I choose the C600 over the SRV850 because the C600 has way more storage and way more features.
I've had several bikes in the past and 1000cc was too much power for the street, but 600cc always leaves you wanting more. Around 800cc is the sweet spot.
Give me a BMW C850 with 100hp and i'm happy.
Assuming of course this even comes out...
