I passed my test Sept 2019. I purchased a Yamaha MT125 to practice on.. sold it on as soon as I passed. Great bike for a learner, looks smart too. I test rode a Street Triple RS.. and its a truly wonderful bike. But the lack of a fairing just made it difficult on fast dual carriageways, espescially if you are carrying some speed. Around 80% of my riding is on fast A roads, so a naked bike is useless for me (even though I admit they are a giggle on a B road!). I bought a 2019 Honda CBR650R in the end. Great for getting some experience, and fast enough for now. Cheap insurance too. My advice.. whittle it down to a few bikes you like, then go test ride them. Hoping to actually get to use the damn thing once the lockdown lifts, for now its just a garage ornament sadly.
