This will give a direct earth.

Also make sure the connections on the positive are good, as have seen dodgy starter solenoid connections give issues, especially if had starting issues before.

Might even be worth putting a screwdriver/jumping the starter solenoid just to confirm not burnt out inside

Would the smaller connections on the solenoid cause any issues? The large terminals are clean and I also have a direct engine ground but the smaller connections on the solenoid which I assume are to just energise the solenoid are a little lose.
I will try jump with screwdriver but this freaks me out a bit I'm useless with electrics and don't want a shock haha

Most are pretty awful quality I've just gone through three battery warranty claims on a works van with supposed premium battery, all shite. Worth trying a direct earth from the starter motor to the frame as well.

Whats a drop test and where would I find a place that does them?

Absolutely buzzing with the amount of replays and new suggestions to try thanks everyone. Will be working on this over next few evenings fingers crossed we get it sorted thanks again!

Scott - getting back to the upgraded starting cables, this is the recognised upgrade for the Sprint ST (and GT) 1050. They're made and supplied by Jeff 'Pudding' Halford here in the UK. Is the Speed Triple the same layout?
On another note, while it's true that the condition and efficiency of the reg/rec, stator and all the relevant connectors won't normally affect engine start per' se (providing the battery is well up to scratch) - it'll sure be critical for getting and keeping the battery there.

I'm sure the length of cables for the speed triple are not the same as the Sprint or other models with the same 1050 engine.
I have also looked into the Jeff "Pudding" starter cable kit. It's great you can get something like this "off the shelf" although I found it much cheaper to get everything I need including a heavy duty crimping tool and do it myself.
Inregards to the RR, I'm planning on upgrading the RR and stator and with more direct thicker wire to boost battery charge as this is also a common thing to do on the earlier Striples. Once I've got the bloody thing starting unassisted
