TT Tech - Sidecar outfits explained 

Fark that's a good question. My curiosity has peeked, hope someone answers. 👍

@@coolhandpuke3780 Yeah I was a little confused, he talked about how they have so much more grip than a motorcycle so surely they should be putting the biggest engines possible? Hopefully someone responds.

So, the sidecars used at the TT are F2 sidecars which are powered by 600cc inline 4 engines or the 675cc 3 cylinder Triumph engine. Up until a couple of years ago the world championship (held on short circuits like motogp or wsb use) F1 sidecars used 1000cc engines, although this has been reduced to 600cc to try and boost participant numbers. F2 chassis have always been favoured at the TT anyway due to their shorter wheel base and better maneuverability. F1 chassis have the engines placed behind the rider and have a significantly longer wheel base. There was a 1000cc F1 sidecar which ran in a parade lap here at the TT a few years ago and I seem to remember it running a pretty quick lap. If you look up images/video of F1 vs F2 sidecars you'll be able to see the difference. Hope this answers your question! 👍

hakkalocken , 👌👌👌 Thanks dude 🤘

You’d think they could squeeze a 1k engine in

The angled steering head causes the front wheel to self centre, if it did not do that it would be far too twitchy to ride.

Yeah, I agree they do have more than 10mm. Apart from the chair wheel which has no suspension at all

Yes I was confused by that. F2 spec is a minimum 20mm en.wikipedia.org/wiki/Sidecar_TT#Formula_Two_Sidecar_TT_Specifications

@J T the brick When I was racing and I'm sure its the same now we used to run pretty low tyre pressures, something like 12 PSI so I guess the tyres also act as suspension.

Too low CoG will push the front end more under braking. And you won't be able to lean it as far as the wide parts of the engine will touch down.

Mid `70s a designer / racer .Who I watched at 1977 TT`s had an outfit that good the passenger was really,just ballast.F.I.M banned it.
