Exept the last ones - because there are no words for it … and in a very simple way - sure:
supermagnetic leans: very strong magnetic fields (like “tractor beams”) that use a magnetic force (that works even on not metallic objects) to pull the bike around corners.
gravity wells: makes parts of the bike more heavy. like mini-black-holes … just more aimed. Also the focuspoints are not to 100% ON the bike. So it drives a curve.
roomwarping bubble: a bit like the “warp engine” in star treck. But with one warpbubble on each side to pull the room around - and to change the course of the bike. You might need a thrid to stabilze the effects - or you may destroy the ground.
quantum dislocations: choose the quantum reality in which the bike is more left or more right. Based on Meta- and Multi-Quantum-Areas and use a Delta to “find” the right one. Needs a lot of power - one or two black holes would be enaugh. 
micro-slipstream-effects: use the hyperroom slipstream around every molecular part on one side of the bike (also this should be balanced in its real speed). So you can “pull one side of the bike” through micro-slipstream to the left and to the right.
partial-time-splays: manipulate the realtime on the left or on the right of the bike. LIke two tank-tracks just on a chronobased streaming-field. You can drive left or right. Or more 
anti-room contortions: supersymmetric anti-room effects - means pull “up” the room until it gets “mirrored” - a bit like a warpbubble but not as “ball”. Could work very well - with the power of a few blackholes and the risk of decronifizise the whole sun system - if your engines get ovearloaded - would be like 1,000,000x the pillar of autumn - or something like that.
Depends on the system.
m/n-axis-drifts: you use some of the dimensions that you don’t notice (String / M-Theory got some already) and use them as “booster” or “anti-booster”. Sure you have to fill something in the dimensional areas first. Then you could use them to stear. For this you need anti-room and anti-time streams -which make everything very … “energy-charged”.
If you don’t dematterialize the bike and sink the room where it was into a m- or n-hole by creating a “black hole” in the timeline (cuz of the counter-time-stream) … Then also the room/energy levels could get out of balance. So the bike might explode into a “little big rip”. Depends on how “strong” your system was. This might pull like 1-3 whole galaxys into thier doom - and destroy some essential parts of the universe structure.
The other ones are even more a waste as a stearing-thing for a bike. If you can manipulate the room-energy-expansion factor you can do a lot of things, than only stear a bike - lol.
And they are even harder to explain. Also iam running out in words for everything. 
“etc. etc. pp.” means also - Iam lacking in words that I can type in here, too. 
(Its very limited in phoneme here.)
Orion10 is right. The most of these things would mean: covenant will be toasted until the war has even began.
Only nozzles or a moving front wheel can be working with the canon - I think. But I know the jet-nozzles are realy hard to control, cuz of the pitch axis. And the front wheel might make the track ripply - same counts for only leaning the bike to the left or to the right or/and bend it.
