The attraction of a px200 is that (if my understanding is correct) they can provide a different level of performance with corresponding tuning. Put in another way, a PX with 20hp should be able to cruise at 60+ if it is set up for torque, and possibly hit 75+ in short bursts. All of a sudden a mountain based tour, even allowing for oxygen starvation due to altitude (am I getting ahead of myself here?) becomes much more attractive. Thinking about it though, a Parmakit ain't that far away from that as it stands! Will your scoot pull these kinda numbers? One thing I will do is ask around my club to see if anyone will help me, though I've already divulged their attitudes to kits!
Brakes, well, I've ridden two T5's, one with a semi-hydraulic disc on the front, the other with Drums. Neither had the 'feel' of the disc on my PX, which is pretty good in comparison (and probably an element of personal preference). Yet riding in central London I have had at least a couple of 'Oh My God, Am I Going To STOP In TIME!' moments due to truly inconsiderate/aggressive/'must get ahead of the bloke on the hair-dryer' driving. I would like to boost the stopping power with better pads (cheap, will do this anyway over the next month or so before season kicks off) and possibly a better disc and calliper eventually, though I don't know the scale of the improvement.
Tubeless rims are great, though I have heard that it can be tricky fitting tyres on them. SIP do them with performers pre-fitted, though it is my understanding that these are a low-mileage tyre and that after a season (3000km's) I would be needing to get them changed. I saw in Scootering Magazine that Pinasco are trialling tubless SPLIT rims! These seem like a much better arrangement, though won't be cheap and probably won't be without teething troubles (maybe?).
The jump from a Pinsaco to a Parmakit is £70. The problem (as I see it, with my limited experience) is getting the rest of the components to deal with such a large power hike (12-16hp). Granted the chassis would be the same as a PX200 or T5 milenium, so theoretically OK(ish) but the crank, clutch and tranny would need upgrading too.
I think for this season it's a case of DR or Pinasco cast iron, probably the three port cast iron pinasco as it's 'designed to work without porting' (their words, not mine), 22tooth clutch cog and SI24 and see where it gets me. Upgrade chassis of bike next season (Shocks, rims, brakes) then possibly look for yet more of the fruity stuff the season after.
The ferry to Spain is £400+ though, better through that into the equation too!
By all means let me know if this seems doomed to failure/mediocrity in your honest opinion!
