2017 t120 for first bike...

So, I've come across a perfect condition, low mileage 2017 Triumph T120 for $5000 (too good to pass up)

I know it's a lot of bike. But I do have ~10 years experience on mountain bikes.

I've already decided on getting a triumph Bonneville and the t120 is the one that really speaks to me.

Should I settle for an older(~2007) 865cc for four grand or get a late model 1200 with ABS and TC for five?

20 years old 160 lbs - I will absolutely respect the bike and it's engine.

Since I first decided on buying a bike, I've had my heart set on a late model t120.

Any input?
