Hey Guy's, I'm sure some of you have been as curious as me as how the Chinese (EDIT~ Taiwanese) 'Maxxis' sport tyres compare to the long-time players in the field. Well me being the sucker that I am, I just had to take the expensive gamble and see. I fitted a pair of 120/70 x 17 and 190/50 x 17's to my stock GSXR1000K6 and will submit additions to this thread as I put them through various track, commute and sport road riding sessions. I will update the subject line with 'part 2' and 3 as I submit my impressions. I don't have the retail prices for the tyres at the moment but will post them soon, but from memory they are not much cheaper than the current crop of the tried & true sport tyres currently on the market, hence no one wanting to take a chance on these tyres. In the last 2 years, on my GSXR, I have used Bridgestone (014 & race 002's), Michelin (Pilot Power and various compound slicks), Dunlop (D208 GPA and various slicks) and Pirelli Dragon slicks. All on the street & track. FITTING Both tyres went on easy, I have found Chinese tyres in the past to have a minutely smaller ID making fitting a little difficult, in fact the rear may be a little to much of an easy fit; after a track day at the Island I found the rear tyre had slipped about 300mm on the rim. I have had this problem with Dunlop front tyres before. Have to be careful to not use too much lube when fitting them. Sidewall stiffness felt much like Michelin Pilots, not as soft as Pirelli's, not as firm as Dunlops. I decided to start with a tyre pressure that generally suits a medium strength carcass (as oppossed to slightly higher for soft tyres or lower for a hard carcass). HANDLING & STEERING On the street the Maxxis tyres give a very neutral steering, no tendancy to 'fall in' when tipping into a corner. The front profile gave light steering at low speeds with minimal 'self steer' over iregular surfaces. The rear also did not display any high speed weave or self steer effects. As far as I am concerned, these Presa sport tyres have given my Gixxer the best around town & bumpy road manners that it has ever had for me. RACE TRACK #1 First time at Phillip Island track, from brand new, with a rusty rider, I used tyre warmers to get them up to temp before venturing out in the fast group. The tyres seemed to take a little longer to scrub in compared to slicks that I generally use; had a front end slide in Honda after a couple of laps and a flick out of the seat on the same corner the next lap. I feel the tyres have good adhesion when cold, compared to other cold tyres but I was finding it hard to keep the tyres warm enough to give good hot adhesion, this could be a trait of most road tyres as they are designed for some longevity, slicks that I generally use on the track don't work as good when cold but have a better hot tyre adhesion factor. I found that the right side of the tyre (the less stressed side at the Island) was not working as well as the left side, I think it was because on the cold day I was not keeping it hot enough. The left side; I had some consistant drifts coming out of Syberia (turn 6) as I was standing the bike up, I think that is atributed to the section of the tyre where most of the grooves are, obviously giving less rubber on the road, plus my throttle hand finding that the safest place to sample traction. My last dry session before lunch had me tagging a couple of racers that were circulating in 1.49ish lap times, the tyres were doing it easy, I was over compensating for a slow entry with a little too much throttle coming out and had a couple of out-of-the-seat moments at Honda (turn 4). I think a warm day at the Island and with me up to speed, I would expect 1.43/44 times easily from these tyres..... we'll see ;-) The day was cold at the Island and the showers came in at midday so I got to evaluate their performance in the wet; with a harder street rubber & minimal grooves I did not expect wet adhesion to be very high and I was right but no more say than a less grooved tyre like a Pilot Race. After the track day, I am using the bike to commute to work, any wear from the track day has not affected the bikes road manners what so ever, in fact, I have never loved riding my bike so much! So at the conclusion of part 1, I have to say that I am impressed with these tyres so far, my next track test will be at Broadford where I have completed thousands of laps around and will better understand adhesion qualities. John PS This is not any form of product promotion, we do not currently carry these tyres in the shop, I genuinely had an interest in these tyres and thought you guys would.
