Iv owned bikes all me life from a kid back in UK, all geared bikes culminating size wise to a Gixxr Thou (K3) my last UK bike (now am an old codger of 57) I sold last year a Triumph Bonneville T100 (865cc) meanwhile here in LOS (Phuket) Have always owned Scoots, CVTs (for a change and easy as) more relaxed vibe and just dont see need IMO for Mental speed, full balls out here in a place where complete Nutters are on the roads. The odd time done big road trips years ago I just hired Big lumps (+750cc) Had a 135cc Yam Nouvo for years, then back in 2016 I bought a Forza 2013 off a mate, low mileage 1 owner.
I still own this bike, Im a lard ar $ e at 18 stone and after few months swapped the rear shocks for YSS with sub tanks, set them to suit me, put Diablos on it, front end was ok bar the Forzas - this earlier model are re-nouned for Fork oil seals (Iv gone through 2 sets to date) and a set of fork tubes (but that maybe due to bike being left nearly 2 years owing to Covid and me stuck in UK) anyway I still love me old forza 300. its also uprated (Modded Variator with revised rollers weights 3x17g 3 x 13g) supplied by Phuket Power (the French Guys down in Rawai, has a unrestricted but baffled exhaust system - these upgrades give a bit more Oomph 0-60 more Torque at expense of top end which I dont need here in LOS.
Bike will do me till am 60 god willing then I my next bike (unless something better on Market for my use) will be the Forza 350 but I will be adding my own upgraded parts, my mate has Ohlins rears on his Forza 350 but was way over priced supplied last year by Honda. I think If the Ohlins are too much I will go with the YSS as they have served me well. My advice is just buy the bike then after a few months see how its bedded in, you can get the shocks and any other upgrades you like yourself, as mentioned Phuket Power do some nice quality upgrades for various bikes mail order or if you in Phuky you can book in by appointment Iv used these guys since 2008 myself always great service with quality parts.
p.s Iv not come across these Nitron shocks before but they dont look that meaty on the pics above? Id be going Ohlins if not much in price or YSS as said as Iv tried & gtested them over last 8 years - Yes my Forza is like a ruddy barge but I can get a weeks shopping in her, or two full face helmets & then some. More than another mate can get in his T-Max lol So for me in Phuky my Forza fits the bill for now, Lady on the back, pulls like a Train and plenty of room and comfartable... a Geared bike here in LOS - No Thanks
