Hey TT members,
Recently I pulled the trigger on a new stock '17SM as a first bike after hearing some of the fantastic reviews it gets here and elsewhere and rode it home stoked as can be this last friday. Stopped off 5 mins away home in a quiet street and got a feel for the thing, some take-offs, shifting, braking etc. was taking it easy but having a blast just with that. During this process I noticed that often when rolling on or off the throttle (to/from idle/freeplay) there can be a bit of a lurch particularly at lower speeds/rpm (coming around a corner etc.). From a bit of trawling around the forums it seems like that this may be 'lugging' the throttle? I guess I was expecting the idle/engaged transition to be a little less jumpy, I guess feathering the clutch at those speeds is required. Anyway I figure way I'll come back to a quiet spot for the next few weeks and build confidence, and particularly master the clutch before I spend too much time on the commute or in heavy traffic.
Fast forward to the next morning. Get up early to avoid traffic and head off to do some more practice. Still noticing the lurch on and off, but trying to be smooth with shifts and matching the downshifts in particular. Lo and behold, I come to a set of lights, and begin to shift down (second to first?) - note, it gets a little hazy here - and quick as you know it, the bike is flapping from side to side, I'm gripping the bars wondering what is happening, and then I'm on my arse sliding down the street at 30kph having looped it out from under me. After going over it in my mind, I'm assuming I must have dropped the clutch during the shift and the sudden acceleration sent me back in the seat due to bad body position not gripping tank hard enough with legs, I instinctively grab the bars harder = more throttle, rest is history. Safe to say it scared the shit out of me and my confidence (and hip/neck) are a little battered. Thankfully helmet and gear did the job except for the jacket riding up during the slide and I'm counting my lucky stars that there wasn't anyone behind me or coming the other way. Bike seems fine, a little scratched is all.
So for the questions. Obviously the above was pretty much completely rider error, and when the body and mind are ready to get back on I want to put the time into improving my skills (the irony of this happening on the way to do so is not lost on me!) I feel very humbled by the experience, and have a good sense of how far I have to go. In that vein, can anybody recommend any videos/instructionals/etc. for the drz or motard style bikes regarding braking, handling, clutch and body positioning? I feel like there's not a huge amount of cross-over from regular street bikes due to the ergonomics and height etc or am I off the mark there? also at the pre-learner course we were warned off using anything less than 4 fingers to brake with, but between the lurch in rolling off the throttle (even just to set up the brakes) and the braking it feels unsteady. Think I will adjust the levers down a bit to make this easier though.
All that being said I'm still wondering about the lurch rolling on and off the throttle. Is this just due to the bike being a single cylinder and liking to rev higher? Is there a way to improve the smoothness from free-play into throttle especially at low speeds? It feels like it comes on and off quite strongly into engine braking at the engagement point. Does this change as the bike breaks in? I noticed that the manual recommends using the clutch below 15kph, though even below around 20 (from the unfortunately VERY limited time i spent on it) the engine was feeling a little unhappy. Just wanted to confirm that this is to be expected
Sorry for the essay and appreciating the time taken.. Think I just needed to get it out my head a bit.
