Actually Dawn, almost ALL sportbikes with a V2 motor use a 90 (mostly) or a 60 degree angle. The 45 degree found in cruisers don't deliver enough of a steady power delivery needed for a sportbike ride return. They also don't have the opposition needed to hold a good handling balance. I'm not aware of a sportbike using a 45 degree V2. Aprilia is the most successful maker of the 60 degree V2 that I can think of, and many riders arguably don't like the motor because it's still too harsh with how it handles. Since I've been admiring the RC51, I believe I'm well aware of how a V2 sportbike using a 90 degree configuration is like. Most of what I posted came directly from riders who've owned and rode both I-4 sportbikes and V2 sportbikes. I've also rode a I-4 (Blackbird) with a V2 (RC51) and this was what I observed. Here's another quote from a road test on a V2 sportbike: "Bottom end pull is excellent and builds into a very strong mid-range. It does suffer a little at the top end compared to the 4-cylinder opposition but so do all V-Twins." http://www.mcnews.com.au/Testing/rsvdyno.htm The Aprilia and Suzuki TL1000 are V2s (one 60 degree and one 90 degree) and the Kawasaki is a I-4 http://www.mcnews.com.au/Testing/tlr_dyno.htm The R1 and ZX are both I-4s and the TL is the V2 Again Dawn, get out of the rags and numbers and go ride the bikes....then talk it. I wasn't in a bunch or had my panties in a bunch (mostly because I know I'm right and you're "reaching"). I'm just pointing out that the power on a V2 motor is down low compared to a I-4. Compared to a F6 from a Valk (which is what Jerry has now anyway) the power from the Bandit would be where the Valk would redline. I've personally rode a Valkyrie, several sizes of I-4s on the YZF and CBR lines, and a V2 with a 90 degree angle....have you?
yep, I have sit on it. I really like the way the seat and gas tank kind of link you to the bike. Call around and find an 07 to look at.
Well that's all very impressive, especially coming from someone who up until a day or two ago didn't know the difference between an SV650 and the Bandit. I am glad to see you have spent a few idle hours over the past couple of days doing your research on bikes and their engines. You still need to understand the difference in how the 90 degree V-Twin displays it's power compared to a typical 45 degree V-twin.
I didn't post it to be "very impressive". You don't know how to compare a dyno run to see what I've said in the beginning was correct. I'm stating facts based on reports, dyno runs...and mostly my own observations. What about you? It's one thing to not know the Bandit isn't an SV model and not knowing how a V2 performs opposed to a I-4. I don't follow the Suzuki line, so I'm not into what type of engines they use. Do you know each and every type of engine in each of the motorcycles made? If you can't understand what I've said in my previous posts, can you look at the dyno chart that I posted a link to and see the colors? The V2 engines peak and have all their power much lower than the I-4. Isn't that what I said before? (forget it, it's rhetorical) Now, for someone who as you say "didn't know the difference between an SV650 and the Bandit", I seem to have known exactly what I was talking about from the start...and haven't changed anything, but rather provided fact after fact to sustain what I said. Dawn, who brought up anything about a 45 degree V2? There's only 1 "sportbike" that I know of that uses a 45 degree V2, and it can't be bought for the street. It's the HD VR1000. Then you have the VRod using the same engine, but that's not a "sportbike", it's in a cruiser class. You're the only one who ever brought up the 45 degree motor. The power is power. You make 120hp, it's the same no matter what type of engine it is. Where it peaks and makes that power is what's different. The reason sportbikes don't use the 45 degree V2 motors has to do with their handling, not a lack of power or torque. You're still reaching.
We are not in a big disagreement on this stuff Brian. My point is, as it was when I first posted to this thread is that the 90 degree V-Twin used in the SV 650 does not make it's maximum power in the low RPM range. Nor does it have the enormous grunt usually associated with the V-Twin. In fact the Dyno curve of the SV 650 is very similar to that of the Bandit. Back to discussing the Bandit, before Christmas I recall reading in an article Suzuki will be introducing a special edition 2008 Bandit into the Canadian market in the spring of 2008. Based on the 07 Bandit the SE will come equipped with ABS brakes, fairing lowers, increased storage capacity and a few other goodies. What was already a very capable bike just got a little better.
I NEVER once said anything about the 90 degree V2 (or even a 60 degree) making it's "maximum power" in the low RPMs. What I said was that the power and torque of a V2 motor is at the lower range as opposed to the I-4 motor. The dyno comparisons back up exactly what I said. The reports back up exactly what I said. I don't have a problem in discussions like this, but please don't insert arguments which don't exist. No, it really isn't. The differences between the other I-4s and the Bandit's I-4 is between water/air cooled motors. The water cooled motors typically go much higher in the ranges and still making increased power. The only reason the SV and Bandit motors look similar is in the linear curves. The same characteristics still exist between the two types of engines. Back to your comment about my "several days of research", I spent all of about 3 minutes tonight between watching ebay auctions, this discussion group and doing the searches to find the web reports to agree with what I said. I've spent several days working and not really reading this group. I got off work and read your response tonight and replied to it. I'm sorry if you feel you're not important enough to me for me to post every time as soon as you post, but it's just the way it is. Tonight I'm more into this group because it's a choice of watching Bush and his smirky faced bullshit on television or discuss motorcycles with you and buy accessories on ebay. Right now, ebay is winning out. Sorry.
The discussion was about the SV650 (90 degree V-Twin) and the in line four Bandit. In this case the torque curves are very close. And I ask the same of you. Let us know what you bought.
