Just wanted to relay my experience today at the Victorian Winchelsea trial.
I gave up my usual ride ('09 TXT250 Gasser) for a TY175.
I should say I'm not a complete TY virgin - a very beat-up TY175 was my first bike as a kid, which I punted through the bush around Ulladulla NSW for a few years as a teenager.
This one however was expertly prepped by Geoff Lewis, and arrived in the factory Yamaha truck (Geoff's yellow van) driven by Tim, as Geoff was crook.
So after 15 years on various Gas Gas's in C+ grade, I rode the 200m to the first section, and decided C grade lines were probably the order of the day, as the classic/twinshock lines looked "too easy".
Well. Was I in for a surprise...
The 175's are not exactly renown for their acceleration capabilities, and this first section involved a steep decent followed by a sharp LH turn and even steeper hill climb. About 3/4 to the top, a wrong line chosen, and that was that. 5.
The next section had C grade doing all sorts of tight turns over large-ish boulders. I decided then that the Classic/TS line was now "probably about right" so reverted to that line for the rest of the day, until I got used to the whole "doesn't go, doesn't stop" way of riding.
And did I enjoy it? Did I what! The Classic lines were far more flowing and really suited to the older bikes. Even though the Classic line had maybe only 1 or 2 markers in the whole section, I found myself putting as much or more thought into the line for each section as I would in C+. I found it critical to pick smooth flowing lines for best chance of a clean.
By the end of the day I thought I probably had enough of an idea on how the bike rode, to have a go at some C grade lines. But by then I was worn out... there is so much more body language required on these bikes compared to a modern.
Thanks heaps Geoff for the bike; maybe I'll brave that Tiger Cub one day...
