bike they wanted, as long as it was Kawasaki’s Ninja 250. Now as manufacturers clamor for market share of coveted new riders, the once stagnant beginner bikes are finally benefitting from R&D attention. The result for consumers is a more robust offering of small-displacement mounts, with the promise of more on the way (see sidebar).

Kawasaki’s Ninja 250 reigned unchallenged for years as the quarter-liter sportbike in America. It faced zero direct competition from Kawasaki’s Big Four rivals, despite the little Ninja’s obvious popularity. Instead, manufacturers seemed content to chase the higher margins afforded by the larger displacement Supersport and Superbike classes. Then the motorcycle market crashed, with the sportbike segment high-siding… Now as the market stabilizes, more manufacturers see wisdom (or is it necessity?) of producing fun, affordable bikes to court a new generation of riders.

Honda was the first to challenge Kawasaki with its CBR250R. The 2011 model year debut showcased some of Honda’s engineering might – with features like the off-set cylinder head on its liquid-cooled Single. It also offered big-ticket newbie-friendly features like optional ABS and linked braking. While it thankfully provided sportbike initiates with a second option, it couldn’t displace the Kawasaki in our 2011 CBR250R vs. Ninja 250R comparison.

See the Ninja 300 battle its entry-level sportbike rival, the Honda CBR250R, in the 2013 Ninja 300 Comparison video.
Two years after the CBR affront, Kawasaki delivers its Ninja 300, powered by a now-296cc Parallel Twin. Those extra 47 cubes impressed during the 300’s First Ride introduction late last year. But the other redesign changes and additions on the Ninja, like its slipper clutch, make this Kawasaki a comprehensively better bike than its predecessor.

The above statement doesn’t bode well for the Honda, of course, but the CBR showed true Samurai spirit by not flinching in this 2013 comparison test. Down 47cc, the CBR squared off against its bigger Ninja rival in MotoUSA’s standard showdown format. Our test kept to the streets (in hopes that we may follow up this year with a track test), with a mix of freeway, city and canyon carving duties surrounding our offices in Southern California. We ran the little rippers on the in-house dyno and weighed them on the scales, as well as gathered the usual performance test data as best we could.

As author of the Ninja 300 First Ride and well-versed with the previous 250 iteration, I serve as author and chief test rider alongside our do-it-all editor/video guru Justin Dawes. Chasing my colleague on Ortega Highway with the throttle pinned, my little CBR screaming at redline… we were far from a triple-digit pace, but both of us were grinning. True, these entry-level bikes are a critical segment for the motorcycle industry. But they also deliver a legitimately fun riding experience. Here’s what we discovered.

The source of the lactic acid has been a matter of debate. Some studies suggest that the presence of estrogen and not Lactobacillus is primarily related to acidification of the vagina,[34][35] and even that lactobacilli cannot produce lactic acid from glycogen.[36] The overall vaginal pH can be attributed to the total of estrogen mediated lactic acid production by the epithelial cells (producing only the L-isomer of lactate) and the lactic acid contribution by the endogenous vaginal bacteria (producing both D- and L-isomers of lactate).[33][37][38] Boskey et al.,[37] studying vaginal lactate production in 11 women, found that D-lactate (bacterial origin) in vaginal secretions ranged from 6% to 75%, with a mean of 55%. They concluded that these findings supported the role of Lactobacillus as the primary source for vaginal acidification, although the wide range found was not indicative for a dominant bacterial source of lactate in all women. Moreover, the midportion of the vagina has a higher pH than the vaginal fornix, although the lactobacilli concentration is uniform throughout the vaginal canal.[33] This is indicative for the fact that the vaginal mucosal metabolism may be more dominant in determining the final pH.[33][39]
However, in a pyrosequencing study by Ravel et al.[40] of the vaginal microflora of 396 asymptomatic North American women, representing four ethnic groups (white, black, Hispanic, and Asian), the higher median pH values in Hispanic (pH 5.0 ± 0.59) and black (pH 4.7 ± 1.04) women reflected a higher prevalence of communities not dominated by Lactobacillus spp. in these two ethnic groups, when compared with Asian (pH 4.4 ± 0.59) and white (pH 4.2 ± 0.3) women. Ravel et al.[40] found that the lowest pH values were associated with vaginal ecosystems dominated by L. iners and L. crispatus, and the highest pH values were associated with vaginal ecosystems not dominated by species of Lactobacillus.[40][41] The results of Ravel may be controversial for L.iners, which was strongly associated with Bacterial vaginosis-like vaginal microflora, which is characterized by alkaline pH.[42][43] Hummelen et al.[41] stated in their pyrosequencing study that L. crispatus is associated with a low pH, but when L. crispatus is not present, a large fraction of L. iners is required to predict a low pH.[41] Nevertheless, these results indicate that bacteria play an important role in the acidification of the vagina and more research, e.g. regarding the resource of glycogen, used to produce lactic acid and regarding the bacterial species that can metabolize glycogen, is needed to understand the various factors that govern vaginal pH.

The concentration of the nerve endings that lie close to the entrance of a woman's vagina (the lower third) can provide pleasurable sensation during sexual activity when stimulated in a way that the particular woman enjoys. However, the vagina as a whole has insufficient nerve endings for sexual stimulation and orgasm,[69][70][71][72] which is considered to make the process of child birth significantly less painful.[70] The outer one-third of the vagina, especially near the opening, contains the majority of the vaginal nerve endings, making it more sensitive to touch than the inner two-thirds of the vaginal barrel.[70][71][72]
The clitoris contains an abundance of nerve endings and is a sex organ of multiplanar structure with a broad attachment to the pubic arch and via extensive supporting tissue to the mons pubis and labia, centrally attached to the urethra and vagina. Clitoral tissue forms a tissue cluster with the vagina. The tissue is more extensive in some women than in others, which may contribute to orgasms experienced vaginally.[69][71][73] During sexual arousal, and particularly the stimulation of the clitoris, the walls of the vagina lubricate. This reduces friction that can be caused by various sexual activities.[11] With arousal, the vagina lengthens rapidly,[8][11] to an average of about 4 in.(10 cm), but can continue to lengthen in response to pressure.[74] As the woman becomes fully aroused, the vagina tents (last ²⁄₃) expands in length and width, while the cervix retracts.[75] The walls of the vagina are composed of soft elastic folds of mucous membrane which stretch or contract (with support from pelvic muscles) to the size of the inserted penis or other object,[11] stimulating the penis and helping to cause the male to experience orgasm and ejaculation, thus enabling fertilization.


Structure of the wall of vagina
An erogenous zone commonly referred to as the G-Spot (also known as the Gräfenberg Spot) is typically defined as being located at the anterior wall of the vagina, about five centimeters in from the entrance. Some women experience intense pleasure if the G-Spot is stimulated appropriately during sexual activity. A G-Spot orgasm may be responsible for female ejaculation, leading some doctors and researchers to believe that G-Spot pleasure comes from the Skene's glands, a female homologue of the prostate, rather than any particular spot on the vaginal wall.[76][77][78] Other researchers consider the connection between the Skene's glands and the G-Spot to be weak.[79][80][81] They contend that the Skene's glands do not appear to have receptors for touch stimulation, and that there is no direct evidence for their involvement.[81] The G-Spot's existence, and existence as a distinct structure, is still under dispute, as its location can vary from woman to woman and appears to be nonexistent in some women,[73][79][82][83] and it is hypothesized to be an extension of the clitoris and therefore the reason for vaginal orgasms.[69][73][84][85]
