Yeah I don't really want to modify the bike.. Did TT design the bike to use the servo as a down travel limiter or is this just an unintentional design flaw? If it's designed like this on purpose I suppose I'll just trust them and let it be...

Also this must be the case for every single SB5 so I'm wondering what everyone is doing about it? Or how is it dealt with on the SB5 RTR?

I don;t know about the design... I have only figured that if you install a servo (specifically the 1251, since it's only one of two servos I've used, read below) with the thick spacers, then the downtravel of the suspension arms is stopped... Even if you dremel some of the lower suspension arm, there's still rubbing or stopping...
I cannot recall what happened with the Ace DS1015, which I first installed, because after a while I sent that fried (due to my fault) servo to TT in Germany and they declared it dead, so I never got it back. However, I do know that the DS1015 (a full size servo) was mounted with no spacers, in order to get that "17mm" horn height, so I GUESS it allowed full travel of the arms.
Speaking of the Savox 1251 low profile, I had it mounted with thick spacers front and rear, in order to get those 17mm... Now without the rear spacer, the top of the servo is at 15.5mm approximately.
In my opinion and I may be TOTALLY WRONG on this, the 17mm horn height was there for a simple reason: So that the steering shock springs do not touch the front of the upper arm and interfere with the freedom of steering movement.
The bike, as built from the kit, is an excellent racing vehicle, in every aspect and needs some fine tuning here and there, applied on its adjustable parts, to be easily driveable by every kind of driver and power system used...
In the end... you will never see two identically set up bikes, and this applies to EVERY make of rc bikes!
I am not defending TT or the SB-5 in any way... I have paid fully for the bike and a ton of spares and options, so I am speaking very freely.
The knowledge base on this particular bike is extremely big as you can see in this and other national fora...

Edit: One more thought, 10 minutes later!
I have the "weird" habit of taking pics of almost every bike at the races... So, back at home, I study each and every one and then I see "small" things that other racers have done... And it's not only my photos... I follow closely pics and videos from almost every rc bike forum I can find, be it German, Spanish, Italian or whatever! Most of the times I just save the pic and take notes...

On another note, a few months ago, I asked from friends around the world to help/show me how to make the SB-5 slimmer...
Having gathered all the info, and after experiencing the "new slim bike" at the RC Bike Worlds, this year, I wrote a small essay (in Greek, I'm afraid!) and posted it at my friends' Greek rc-news site
Here's the article:
This is the full article with pics from the people I asked for help!
You can use a translator and give it a try on how Greek is translated to your local language!

Well it's 11.40 pm and I've just finished getting the bike ready for tomorrow night. The things we do!

Steliosh thanks for all the information I appreciate you sharing your knowledge and experience with the SB5. I took some things onboard from your post on the previous page. I've installed a limiter and have the bike at 32mm from the battery to the ground when lifting the front. I have 27mm from battery to ground at the front and rear as the bike sits. I am courious if this sounds right?

Other thing is I only had 3000 cst so used that front and rear shocks with orange springs. I did open the piston holes just a little. It feels ok. Using two hole three dot piston ( I am not sure what the dots mean). I removed the spaces from the servo and had to dremel just a little. Using a savox also but I have a different set up with steering rod and springs on one side and a damper fixed to a bracket on the other. I have been using this set up and it works well for me. I also installed modifed headset with set screws.Tomorrow I hope to install the new light scale swingarms.
I also have the aluminum hub set with the weights installed at the stage. See how it goes tomorrow night!

RC Bike Starting Stand!

It's not SB-5 specific, but... I had been seeing these things being used at the Worlds I have attended (OK, the only races I ever raced!) so I had to make one too!
I visited my local DIY woodwork shop, bike in hand (I answered all TradeMarked questions from shop owners and customers, the usual stuff!) we did some measuring, after I explained what I wanted and five minutes later I was presented with 4 pieces of wood!
I screwed a few screws on them, pasted a few stickers and presto!

Shown also is the pic I showed to the guys there! It's Andrea Selva's bike at Riccione RC Bike Worlds, on Thomas Feilner's standing stand!

Oh and the cost: 2.50 euros for the wood pieces...

To be thoroughly tested at my local track tomorrow!!!!!

I have not tested it yet!!!! It just might push the box backwards and the bike spin in the same place!
Will that do?!!!
But... tomorrow I will try to park it backwards...
