Just made few mods on my '12 M1100evo and I'd like to know what everyone thinks?

[desmodoktor]

hello everyone , hope all of you are well!
its been a very long time since i've been here.
I made a few modifications on my monster and i would like your honest opinions?

2012 Ducati Monster 1100evo.
about 6000 miles on it. with a bazzaz zfi and gpr slip on.

Im installing the following:

Racetech springs and changing the fork oil to 7.5W (the stock are way to soft) i weight 190lb with gear on.
Renthal 14T front sprocket (stock rear sprocket and chain)
Pirelli Diablo Supercorsas F:120/70ZR17 , R:200/55ZR17. (got them for free)

how all that going to affect the performance and handling of the bike ? (street and canyon riding not track)


thank you.

Pictures? 

I hope your new springs are linear.... I think the Monsters are sporty enough to deserve that. Plan to change the rear spring too?

Freebies are great, but a 200 tire just doesn't fit your wheel - it's forced into a wrong shape and won't ride like it's designed to.

The lighter gearing of a 14T is almost always welcome

Will be interesting to see how "oval" the rear Pirelli is at 200 rather than "round" on the 5.5" rim. I have found Pirellis to be not as fat a tyre as say Dunlops. You may have got away with a 190, but 200 will probably be too much. Depends too on the rim shape, as I have heard of Supersport Gixxers going as far as 200 with race tyres, but that is a different rim and tyre design.

Issues of chain and swingarm clearance, instability and the tyre causing the bike to fall in due to too tall a profile can all be a hazard. Try and swap the 200 for a 180 somehow.

The 200 series tire will work fine if it clears the swingarm. I know the 848s (also a 5.5-inch wide wheel) require a spacer to run a wider tire. I'm not sure exactly what interferes on the 848 (i.e., swingarm or chain), just that a spacer of some sort is required.

A 6-inch wide wheel is better for a 200 tire of course, but I've raced a 200 tire (Dunlop - slick) on a 5.5" rim without a problem (2003 R6). I would have preferred a 190, but I was using the same pool of tires on the R6 and RSV4 to save money. Your 200 should be fine for the street...so it will just depend on how you think it feels. It will surely affect how the bike tips in.

Glad you chimed in, according to a racer/team mechanic buddy, 200 tyres have been used in our domestic Supersport class with race tyres that have a strong sidewall. I think they were the Dunlop control tyre which are very strong on the sidewall. I dunno how that will translate to the Pirellis in question on the Monster rim, but on the 600 rims they run them which are usually 5.5" to 5.75". That sound right to you JJJ?

I personally don't like to change OEM sizing either in cars or bikes; if I do, the replacing size must be within 3%-5% of the OEM specially if the vehicles have ABS or TC, sizing affects how the control units read the information and how they transmit it to the actuator . . .

Had a guy who insisted he wanted a 150/70-17 on the rear of his Honda CBR250 . .  guess what, bike became slower and "tipsier" on turns, he has the feeling he's gonna fall everytime he comes into a turn . . . maybe the wider tire will add surface making your turn in slower and making you feel the bike is heavier . . . just my 0.02 . . .

OEM for oil is 7.5W

200 seems to be the standard now for slicks, whether 600 or 1000 cc bikes, for better or worse. I run Dunlop, but I'm pretty sure Pirelli did the same (they both make great tires). I think if you're running DOT race tires (slicks with minimal siping) instead of slicks, then 190s are still common. I don't know all the rim sizes...just that R6 is 5.5", and RSV4 is 6"...everyone is running mainly 200s though like you said.

Personally, I like the 190 better on the middleweight bikes due to their rim width. The smaller width tire gives you a larger contact patch when leaned over due to the tire not being overly bent to fit a "narrow" rim. I don't think this would be noticeable on the street, but when racing my 600 rear seemed to slide more than my 1000 mid-corner...which I didn't expect, and I attributed to the smaller contact patch caused by the 200 tire being forced to fit a 5.5" rim. That said, it worked, I just preferred the feel of a 190. If I was going to race a 600 this season I would go back to a 190 DOT tire if possible. On my RSV4 with a 6" rim, the 200 tire is much preferred.

Dunlops traditionally have much stiffer sidewalls than Pirelli. Recently it seems that Dunlops have gotten a tad softer, and Pirellis quite a bit stiffer...but there is still a difference. I don't really have a preference though (I run whoever makes it more affordable for me)...they both work great, and people run 200s from both makes on 5.5" rims.

Like Last in Line said though, it will affect handling. If the OP wasn't getting the Supercorsas for free I'd also say just stick with OEM sizing. I also have no idea how it will affect the TC/ABS (I always forget about that). My Aprilia has a calibration feature to account for different tire sizes, but as far as I know Ducatis do not (lame). That should definitely be considered.

thank you all for your answers.
here are some pictures :


















it fits fine and there is clearance on the swing arm , fender , chain.
haven't ridden the bike yet due to cold weather .

Just looks "rounder". . .flatter in the center . . .
